Abstract
After infection of Escherichia coli with T4 phage, phospholipid synthesis continued but at a reduced rate. The same phospholipid components were synthesized as in uninfected cells; however, the relative rates of (32)P(i) incorporation into phosphatidylglycerol (PG) and phosphatidylethanolamine (PE) were altered. This alteration was most pronounced during the first 10 min after infection. Under these conditions, the isotope incorporated into PG equaled or exceeded that found in PG from uninfected cells. Chloramphenicol (CM) added before, but not 5 min after, infection inhibited the relative increase in PG synthesis, and CM added at different times after infection indicated that a protein synthesized between 3 and 6 min was required for this change to occur. Supplies of exogenous l-serine or l-alpha-glycerol-P failed to affect the relative rates of (32)P(i) incorporation into PG and PE by infected or uninfected cells. Phospholipid synthesis was somewhat higher after infection with T4rII mutants than after infection with wild-type phage. After infection with these mutants or several amber mutants, the relative synthesis of PG and PE was characteristic of T4r(+)-infected cells. The phospholipid synthesized after infection did not rapidly turn over, but infection accelerated the loss of PG synthesized prior to infection.

Abstract
The methylenetetrahydrofolate dehydrogenase of the amethopterin-resistant strain Streptococcus faecium var. durans A(k) was purified 100-fold. Because it is extremely labile, this enzyme required protection by 1 mm nicotinamide adenine dinucleotide phosphate (NADP(+)) during purification; 0.01 mm EADP(+) with 0.1% bovine plasma albumin stabilized the purified enzyme during storage at -20 C. Although the enzyme has properties of sulfhydryl enzymes, thiol compounds were not stabilizers. Oxidation of methylenetetrahydrofolate, catalyzed by the purified enzyme preparation, is NADP(+)-specific and yields methenyltetrahydrofolate and the reduced pyridine nucleotide. K(m) values for NADP(+) and for 5,10-methylenetetrahydrofolate (prepared as the formaldehyde adduct of biologically synthesized l,l-tetrahydrofolate) were calculated to be 0.021 and 0.026 mm, respectively. Neither purine bases and their derivatives nor serine inhibited the reaction. In growing cultures, the differential rate of synthesis of the methylenetetrahydrofolate dehydrogenase was dependent upon the composition of the medium. A medium which contained acid-hydrolyzed casein, and thus an exogenous source of serine, was repressive for this enzyme. In a serine-free, completely defined medium, the amount of folate added (for serine synthesis de novo) affected the duration of the initial exponential growth phase. At the termination of this phase, which primarily reflected the onset of a decreased rate of serine biosynthesis, synthesis of the methylenetetrahydrofolate dehydrogenase was derepressed. Exogenous serine in the completely defined medium prevented the derepression. Furthermore, physiological concentrations of l-serine were repressive not only for the dehydrogenase but also for the methenyltetrahydrofolate cyclohydrolase and the serine hydroxymethyl-transferase. Concomitantly, the differential rate of synthesis of the formyltetrahydrofolate synthetase of S. faecium var. durans A(k) was increased. Apparently, serine regulates the differential rates of syntheses of these enzymes.

Abstract
Filamentous cells of Erwinia sp. produced by growth in the presence of D-serine possess nuclear bodies that are not dividing normally. The nuclear bodies can be highly convoluted and continuous throughout large portions of the filaments. Possible reasons for failure of the nuclear body to periodically divide and suggested relationships to division of the cell are discussed.

Abstract
Gram-negative, polar-flagellated bacteria isolated from the Atlantic Ocean using thiosulfate or elemental sulfur as the sole energy source are considered members of the genus Thiobacillus. These cultures require seawater in the medium although they grow optimally when the salinity is reduced to a range of 6.4 to 25.8 p.p.t. There is no growth at 0 salinity and a 25–30% reduction of thiosulfate oxidation in 3 weeks is observed at 18 °C in a salinity of 32.3 p.p.t. The pH of the medium decreased from 7.2 or 5.6 to a final pH of 2–3. One culture decreased the pH to only 5.0 while oxidizing 80% of the thiosulfate. One representative culture, WH-2, was able to oxidize only thiosulfate and elemental sulfur from a series of substrates including tetrathionate, sulfite, sulfur-containing amino acids, and mineral sulfides. This culture is a strict aerobe and did not grow in the presence of 0.01% yeast extract, 2216E, or nutrient broth.The ultrastructure of culture WH-2 indicates that it is very similar to that of Thiobacillus thioosidans. The cells indicate a substantial cell envelope, cytomembranes, electron-dense fibrillar nuclear material, unknown granules, and distinct polyphosphate granules.

Abstract
Extracts of Saccharomyces cerevisiae were used to develop a cell-free system capable of converting the beta-carbon of serine into the methyl group of methionine. No requirement for either S-adenosylmethionine or S-adenosylhomocysteine could be demonstrated for net methionine biosynthesis. Growth of the cells in B(12) did not affect the reaction. The mechanism for the methylation of homocysteine in yeast appears to be similar to the non-B(12) system in Escherichia coli.

Abstract
We have isolated 40 mutants of Escherichia coli which are nonchemotactic as judged by their failure to swarm on semisolid tryptone plates or to make bands in capillary tubes containing tryptone broth. All the mutants have normal flagella, a fact shown by their shape and reaction with antiflagella serum. All are fully motile under the microscope and all are sensitive to the phage chi. Unlike its parent, one of the mutants, studied in greater detail, failed to show chemotaxis toward oxygen, glucose, serine, threonine, or aspartic acid. The failure to exhibit chemotaxis does not result from a failure to use the chemicals. The swimming of this mutant was shown to be random. The growth rate was normal under several conditions, and the growth requirements were unchanged.

Abstract
Adler, Julius (University of Wisconsin, Madison). Effect of amino acids and oxygen on chemotaxis in Escherichia coli. J. Bacteriol. 92:121-129. 1966.-Motile cells of Escherichia coli placed at one end of a capillary tube containing a mixture of the 20 amino acids commonly found in proteins migrate out into the tube in two bands. The bands are clearly visible to the naked eye, and they can also be demonstrated by microscopy, photography, and densitometry, and by assaying for bacteria throughout the tube. The occurrence of more than one band is not due to heterogeneity among the bacteria, since each band can be used over to give rise to two again. The first band uses all the oxygen to oxidize portions of one or more of the amino acids, including serine, and the second band consumes the residual serine anaerobically. The results are interpreted to mean that E. coli shows chemotaxis toward oxygen and serine. When no energy source is added to the medium, a band of bacteria still appears. It consumes all the oxygen to oxidize an endogenous energy source. The addition of any one of 10 oxidizable amino acids stimulates the rate of travel of this band. Alanine, an example that was studied in detail, supports such a band that consumes all the oxygen to oxidize a portion of the alanine. Serine, the only amino acid that this strain can use either aerobically or anaerobically when grown under the conditions used here, gives rise to two bands.

Abstract
SUMMARY
Bovine growth hormone (BGH) was acetylated with acetic anhydride under a variety of conditions and the optimal conditions defined to obtain a growth hormone inhibitor. Acetyl BGH as well as acetyl thyrotrophin, acetyl bovine serum albumin and acetyl lactalbumin in equivalent doses inhibited the growth response of hypophysectomized and intact rats to unmodified bovine growth hormone. N-acetyl dl-proline and O-acetyl dl-serine of many amino and hydroxyl acetyl amino acids also inhibited BGH but in a higher molar dose than that of the acetyl proteins.
