Abstract
Paramagnetic chemical probes have been used in electron paramagnetic resonance (EPR) and nuclear magnetic resonance (NMR) spectroscopy for more than four decades. Recent years witnessed a great increase in the variety of probes for the study of biological macromolecules (proteins, nucleic acids, and oligosaccharides). This Review aims to provide a comprehensive overview of the existing paramagnetic chemical probes, including chemical synthetic approaches, functional properties, and selected applications. Recent developments have seen, in particular, a rapid expansion of the range of lanthanoid probes with anisotropic magnetic susceptibilities for the generation of structural restraints based on residual dipolar couplings and pseudocontact shifts in solution and solid state NMR spectroscopy, mostly for protein studies. Also many new isotropic paramagnetic probes, suitable for NMR measurements of paramagnetic relaxation enhancements, as well as EPR spectroscopic studies (in particular double resonance techniques) have been developed and employed to investigate biological macromolecules. Notwithstanding the large number of reported probes, only few have found broad application and further development of probes for dedicated applications is foreseen.

Abstract
We have constructed eight anticodon-modified Escherichia coli initiator methionine (fMet) tRNAs by insertion of synthetic ribotrinucleotides between two fragments ('half molecules') derived from the initiator tRNA. The trinucleotides, namely CAU (the normal anticodon), CAA, CAC, CAG, GAA, GAC, GAG and GAU, were joined to the 5' and 3' tRNA fragments with T4 RNA ligase. The strategy of reconstruction permitted the insertion of radioactive 32P label between nucleotides 36 and 37. tRNAs were microinjected into the cytoplasm of Xenopus laevis oocytes, and the following properties were evaluated: the stability of these eubacterial tRNA variants in the eukaryotic oocytes; the enzymatic modification of the adenosine at position 37 (3' adjacent to the anticodon) and aminoacylation of the chimeric tRNAs by endogenous oocyte aminoacyl-tRNA synthetases. In contrast to other variants, the two RNAs having CAU and GAU anticodons were stable and underwent quantitative modification at A-37. These results show that the enzyme responsible for the modification of A-37 to N-[N-(9-beta-D-ribofuranosylpurine-6-yl)carbamoyl]threonine (t6A) is present in the cytoplasm of oocytes and is very sensitive to the anticodon environment of the tRNA. Also, these same GAU and CAU anticodon-containing tRNAs are fully aminoacylated with the heterologous oocyte aminoacyl-tRNA synthetases in vivo. During the course of this work we developed a generally applicable assay for the aminoacylation of femtomole amounts of labelled tRNAs.

Abstract
The dihydrouracil residue at position 20 of Escherichia coli tRNAGly1 has been replaced by the photoaffinity reagent, N-(4-azido-2-nitrophenyl)glycyl hydrazide (AGH). The location of the substituent was confirmed by the susceptibility of the modified tRNA to cleavage with aniline. When N-acetylglycyl-tRNAGly1 derivatized with AGH was bound noncovalently to the P site of E. coli 70 S ribosomes, 5-6% on average was photochemically cross-linked to the ribosomal particles in a reaction requiring poly(G,U), irradiation and the presence of the AGH label in the tRNA. Approximately two-thirds of the covalently attached tRNA was associated with 16 S RNA in the 30 S subunit. This material was judged to be in the P site by the criterion of puromycin reactivity. As partial RNAase digestion of the tRNA-16 S RNA complex produced labeled fragments from both 5' and 3' segments of the rRNA, there appeared to be more than one site of cross-linking in the 30 S subunit. The small amount of N-acetylglycyl-tRNAGly1 associated with the 50 S subunit was also linked mainly to rRNA, but it was not puromycin-reactive.
