Abstract
We cloned, expressed, and purified the Escherichia coli YggH protein and show that it catalyzes the S-adenosyl-L-methionine-dependent formation of N(7)-methylguanosine at position 46 (m(7)G46) in tRNA. Additionally, we generated an E. coli strain with a disrupted yggH gene and show that the mutant strain lacks tRNA (m(7)G46) methyltransferase activity.

Abstract
The rates of the cross-aminoacylation reactions of tRNAs(Met) catalyzed by methionyl-tRNA synthetases from various organisms suggest the occurrence of two types of tRNA(Met)/methionyl-tRNA synthetase systems. In this study, the tRNA determinants recognized by mammalian or E. coli methionyl-tRNA synthetases, which are representative members of the two types, have been examined. Like its prokaryotic counterpart, the mammalian enzyme utilizes the anticodon of tRNA as main recognition element. However, the mammalian cytoplasmic elongator tRNA(Met) species is not recognized by the bacterial synthetase, and both the initiator and elongator E. coli tRNA(Met) behave as poor substrates of the mammalian cytoplasmic synthetase. Synthetic genes encoding variants of tRNAs(Met), including the elongator one from mammals, were expressed in E. coli. tRNAs(Met) recognized by a synthetase of a given type can be converted into a substrate of an enzyme of the other type by introducing one-base substitutions in the anticodon loop or stem. In particular, a reduction of the size of the anticodon loop of cytoplasmic mammalian elongator tRNA(Met) from 9 to 7 bases, through the creation of an additional Watson-Crick pair at the bottom of the anticodon stem, makes it a substrate of the prokaryotic enzyme and decreases its ability to be methionylated by the mammalian enzyme. Moreover, enlarging the size of the anticodon loop of E. coli tRNA(Metm) from 7 to 9 bases, by disrupting the base pair at the bottom of the anticodon stem, renders the resulting tRNA a good substrate of the mammalian enzyme, while strongly altering its reaction with the prokaryotic synthetase. Finally, E. coli tRNA(Metf) can be rendered a better substrate of the mammalian enzyme by changing its U33 into a C. This modification makes the sequence of the anticodon loop of tRNA(Metf) identical to that of cytoplasmic initiator tRNA(Met).

Abstract
Using synthetic oligonucleotides, we have constructed 17 tRNA suppressor genes from Escherichia coli representing 13 species of tRNA. We have measured the levels of in vivo suppression resulting from introducing each tRNA gene into E. coli via a plasmid vector. The suppressors function at varying efficiencies. Some synthetic suppressors fail to yield detectable levels of suppression, whereas others insert amino acids with greater than 70% efficiency. Results reported in the accompanying paper demonstrate that some of these suppressors insert the original cognate amino acid, whereas others do not. We have altered some of the synthetic tRNA genes in order to improve the suppressor efficiency of the resulting tRNAs. Both tRNA(CUAHis) and tRNA(CUAGlu) were altered by single base changes, which generated -A-A- following the anticodon, resulting in a markedly improved efficiency of suppression. The tRNA(CUAPro) was inactive, but a hybrid suppressor tRNA consisting of the tRNA(CUAPhe) anticodon stem and loop together with the remainder of the tRNA(Pro) proved highly efficient at suppressing nonsense codons. Protein chemistry results reported in the accompanying paper show that the altered tRNA(CUAHis) and the hybrid tRNA(CUAPro) insert only histidine and proline, respectively, whereas the altered tRNA(CUAGlu) inserts principally glutamic acid but some glutamine. Also, a strain deficient in release factor I was employed to increase the efficiency of weak nonsense suppressors.

Abstract
Nucleotide sequences of E. coli tRNAs and RNA I or RNA II (controlling replication of ColE1 plasmids) were compared using the computer. The homology between some of these molecules is over 60%. The distribution of homologous nucleotides among the functional elements (stems and loops) of either RNA I or RNA II and the tRNAs molecules was studied. It was found that the homologous domains are located mainly in the loop regions of RNA I or RNA II. A consensus sequence, the nonanucleotide AGUUGGUAG, was discovered in loop II of RNA I and in the dihydrouridylic loop of tRNAs showing homology with RNA I. Based on this observation, a hypothesis was drawn for a possible role of the tRNAs in the regulation of plasmid DNA replication.

Abstract
Mutations that map in or delete the attenuator of the threonine (thr) operon of Escherichia coli were isolated and characterized. These mutations disrupt or delete the transcription termination structure encoded by the attenuator leading to increased transcriptional readthrough into the thr operon structural genes. Most of the base substitutions and single base-pair insertions and deletions map in the G + C-rich region of dyad symmetry in the attenuator and decrease the calculated stabilities of the attenuator RNA secondary structures to similar extents (from -30.8 kcal/mol to approximately -21 kcal/mol). Most of the mutants showed a three- to fourfold increase in homoserine dehydrogenase (thrA gene product) synthesis relative to the wild-type parent strain. The mutation in one mutant (thrL153 + G) lowered the calculated stability of the RNA secondary structure only slightly (from -30.8 to 27.8 kcal/mol) but the mutant still exhibited high levels of homoserine dehydrogenase synthesis. In addition, three base substitution mutants (thrL135U, thrL139A and thrL156U) showed only slightly (1.5 to 2-fold) elevated levels of homoserine dehydrogenase activity, even though the calculated stabilities of the attenuator RNA secondary structures were reduced as much as most of the other mutants. Two of the mutations (thrL135U and thrL156U) mapped in the G + C-rich-A + T-rich junction of the attenuator. The third mutation (thrL139A) creates an A X C pair in the center of the G + C-rich region of the attenuator stem. The results obtained for these mutants show that the stability of the RNA secondary structure does not always correlate with the efficiency of transcription termination. Finally, analysis of the base changes in the substitution mutations showed that the mutational changes do not appear to be random.

Abstract
The DNA sequence of a cluster of twenty-one tRNA genes distal to a rRNA gene set in B. subtilis was determined. None of the tRNA genes are repeated in the sequence. The only classes of tRNAs that are not represented are those for cysteine, glutamine, tryptophan, and tyrosine. Three of the tRNA genes in this cluster do not have the 3'-CCA sequence encoded in the gene. There is no RNA polymerase terminator sequence in the region between the 5S gene and the first tRNA gene or within the tRNA gene cluster. A terminator sequence was found directly after the last tRNA gene. This rRNA and tRNA gene cluster probably represents one transcriptional unit. However, there may be an RNA polymerase promoter site within this sequence, which raises some interesting questions concerning the regulation of transcription for these tRNA genes.

Abstract
The alkylation by ethylnitrosourea of phosphodiester bonds in yeast tRNAPhe, tRNAVal and in Escherichia coli tRNAGlu, tRNAfMet, tRNAmMet and tRNAPhe was investigated under various conditions. In unfolded tRNAs the reactivities of phosphates in various positions toward the reagent were similar. In the folded tRNAs remarkable differences in reactivities of phosphates located in various positions of the molecules were observed. In yeast and E. coli tRNAPhe, reactivities of phosphates in positions 9, 10, 11, 19, 49, 58, 59 and 60 were found to be strongly decreased. Some decrease in reactivity was observed for phosphates 23 and 24. Spermine and ethidium bromide did not influence the pattern of phosphate alkylation in the T psi C arm of yeast tRNAPhe. Our solution results fit with the crystal structure of tRNAPhe with respect to the potential availability of the phosphates in this tRNA to solvent as shown by others. Judging from the pattern of phosphate reactivities, the structure of E. coli tRNAPhe is very similar to that of yeast tRNAPhe. Upon thermal denaturation of the yeast tRNAPhe, the reactivity of the low-reactive phosphates increased, demonstrating a cooperative melting curve. A comparison of the patterns of phosphate alkylation in several tRNAs, essentially in their T psi C arms, revealed a striking similarity, suggesting that the folding of these tRNAs is essentially similar.

Abstract
The nucleotide sequence of spinach chloroplast methionine elongator tRNA (sp. chl. tRNAm Met) has been determined. This tRNA is considerably more homologous to E. coli tRNAm Met (67% homology) than to the three known eukaryotic tRNAm Met (50-55% homology). Sp. chl. tRNAm Met, like the eight other chloroplast tRNAs sequenced, contains a methylated GG sequence in the dihydrouridine loop and lacks unusual structural features which have been found in several mitochondrial tRNAs.

Abstract
Non-initiator methionine tRNA (tRNAMet) was purified from Bacillus subtilis W 168 by a consecutive use of several column chromatographic systems. The nucleotide sequence was determined to be p-G-G-C-G-G-U-G-U-A-G-C-U-C-A-G-C-G-G-C-D-A-G-A-G-C-G-U-A-C-G-G-U-U-C-A-U-m6A-C-C-C -G-U-G-A-G-G(m7G)-U(D)-C-G-G-G-G-G-T-psi-C-G-A-U-C-C-C-C-U-C-C-G-C-C-G-C-U-A-C- C-A-OH. The nucleosides of G46 and U47 were partially modified to m7G and D, respectively. The nucleotide sequence shows a unique feature that the position adjacent to 3'-end of the anticodon C-A-U is occupied by m6A, not by t6A, although the tRNAMet belongs to a groups of tRNAs which recognize codons starting with A.

Abstract
The contents of 2'-O-methylguanosine and 1-methyladenosine in unfractionated tRNA obtained from Thermus thermophilus HB27 were found to increase significantly when the bacterium was grown at a higher temperature (80 degrees C). S-Adenosyl-L-methionine-dependent tRNA (guanosine-2')-methyltransferase (EC 2.1.1.34) and tRNA (adenine-1)-methyltransferase (EC 2.1.1.36) were detected in a cell-free extract of the thermophile, and both of them were partially purified. tRNA (guanosine-2')-methyltransferase specifically catalyzed the methylation of the guanylate residue at position 19 from the 5' end of Escherichia coli tRNAMetf. The amounts of these methyltransferases in the cells and their thermal characteristics seemed to be independent of the growth temperature of the bacterial cells from which the enzymes were extracted. It was inferred that the temperature dependence of the methylation process in vivo is accounted for, not by temperature dependence of enzyme formation, but by that of the enzyme activity.

Abstract
The structure and organization of the gene clusters coding for the two tyrosine-accepting tRNA species (tRNA1Tyr and tRNA2Tyr) on the E. coli chromosome have been determined. The mature structural sequences of the two tRNATyr genes, located on opposite sides of the E. coli chromosome, differ by only 2 bp, but sequences surrounding these portions of the genes are very different. The genes coding for tRNA1Tyr (tyrT) comprise two mature structural sequences separated by a 200 bp "intergenic spacer." It is known that in transducing phage, the region adjoining the CCA end of the second mature structural sequence comprises a 178 bp repeated sequence which contains an in vitro, rho-dependent transcriptional termination site. We find that these potentially genetically unstable repeated sequences are present in the E. coli chromosome with the same organization as that determined from transducing phage analyses. The gene that codes for tRNA2Tyr (tyrU) is present in a single copy and is tightly clustered with three other tRNA genes. One of these genes (to be called thrU) encodes a previously undescribed tRNA (to be called tRNA4Thr). The organization of this cluster on the E. coli chromosome is tRNA4Thr--8 bp--tRNA2Tyr--115 bp--tRNA2Gly--6 bp--tRNA3Thr. The importance of correlating structural analyses derived from specialized transducing phage with those determined for the chromosome itself is demonstrated by results which show that out of four independently isolated tRNATyr transducing phage, two carrying the tRNA1Tyr genes [phi80psu3+,- (Cambridge) and phi80sus2psu3+ (Kyoto)] and two carrying the tRNA2Tyr gene (lambdarifd 18 and lambdah80dglyTsu+36), only the first phage from each group has the same gene organization as that found in the E. coli chromosome.

Abstract
Eight class I tRNA species have been purified to homogeneity and their proton nuclear magnetic resonance (NMR) spectra in the low-field region (-11 to -15 ppm) have been studied at 360 MHz. The low-field spectra contain only one low-field resonance from each base pair (the ring NH hydrogen bond) and hence directly monitor the number of long-lived secondary and tertiary base pairs in solution. The tRNA species were chosen on the basis of their sequence homology with yeast phenylalanine tRNA in the regions which form tertiary base pairs in the crystal structure of this tRNA. All of the spectra show 26 or 27 low-field resonances approximately 7 of which are derived from tertiary base pairs. These results are contrary to previous claims that the NMR spectra indicate the presence of resonances from secondary base pairs only, as well as more recent claims of only 1-3 tertiary resonances, but are in good agreement with the number of tertiary base pairs expected in solution based on the crystal structure. The tertiary base pair resonances are stable up to at least 46 degrees C. Removal of magnesium ions causes structural changes in the tRNA but does not result in the loss of any secondary or tertiary base pairs.

Abstract
Escherichia coli K-12 hisT mutants were isolated, and their properties were studied. These mutants are derepressed for the histidine operon, map close to the purF locus at about 49.5 min on the E. coli linkage map, and lack pseudouridylate synthetase activity. The defect in this enzyme leads to the absence of pseudouridines in the anticodon loop of several transfer ribonucleic acid species, as evidenced by the altered elution profile on reversed-phase chromatography and resistance to amino acid analogues. Finally, the hisT mutants studied have a reduced growth rate that appears to be linked to hisT, although it is not known whether it is due to the same mutation. The normal generation time can be restored by supplementing the medium with adenine, uracil, and isoleucine.

Abstract
The major form of methionine tRNA operational in the elongation of protein synthesis in mouse myeloma cells was purufied from these cells after they had been cultured in the presence of [32P]-phosphate. This [32P]tRNA4-Met species was then digested with T1 RNase or pancreatic RNase so as to obtain both complete and partial RNase digestion products. The nucleotide sequences of these fragments were analysed to enable the derivation of the complete primary structure of this tRNA. tRNA4-Met of mouse myeloma cells is 76 nucleotides in length and contains 15 modified nucleotides. It is the only tRNA yet sequenced which has been found to possess the minor nucleoside 2-methylguanosine (m2G) within the amino acid (a) stem, and also to have an anticodon (c) stem of only 4 and not 5 base-pairs. The loop IV sequence of eukaryotic initiator methionine tRNA (tRNAf-Met) species, -A-U-C-G-m1A-A-A-, IS NOT FOUND IN TRNA4-Met and is therefore absent from at least one of the methionine tRNAs functioning in polypeptide elongation in mammalian cells. This is consistent with the suggested importance of this loop structure in the initiator function of tRNAf-Met in eukaryotic organisms. Three distinct regions of the tRNA cloverleaf, the (b) stem, the anticodon loop (loop II), and loop III, are substantially conserved in structure between tRNAf-Met and tRNA4-Met of mouse myeloma cells. These regions of the structures of mammalian methionine tRNAs probably do not determine whether a certain tRNA-Met will function in the initiation or elongation of protein synthesis, although they might be important in tRNA-Met recognition if the different cytoplasmic tRNA-Met species of mammalian cells are aminoacylated by a single activating enzyme.
