Biochemical studies of bacterial sporulation and germination. XIX. Phosphate metabolism during sporulation.
Acid-soluble phosphate compounds represent about 25 % of the total phosphate of Bacillus megaferium vegetative cells, but only 7% of the total phosphate in dormant spores. In vegetative cells, 12 compounds make up 90% of the acidsoluble phosphate. These same compounds predominate throughout growth and early sporulation, although their relative amounts change during the process. One hour before ...
متن کاملBiochemical studies of bacterial sporulation and germination. XV. Fatty acids in growth, sporulation, and germination of Bacillus megaterium.
The levels of fatty acids and their distribution were determined in cultures of Bacillus megaterium during growth, sporulation, and germination. Branched-chain pentadecanoates (br-C15) were the principal fatty acids of log-phase cells. Synthesis of branched-chain tetradecanoates (br-C14) during sporulation increased the relative proportion of these branched fatty acids in sporulating cells and ...
متن کاملBiochemical studies of bacterial sporulation and germination. XIV. Phospholipids in Bacillus megaterium.
The principal phospholipids of Bacillus megaterium throughout the cycle of growth and sporulation were found to be phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, and a hitherto unidentified isomer of glycosaminyl-phosphatidylglycerol. Phosphatidylglycerol predominated during vegetative cell growth and then declined as spores developed, whereas diphosphatidylglycerol bec...
متن کاملBiochemical studies of bacterial sporulation and germination. X. Ribosomes and nucleic acids of vegetative cells and spores of Bacillus megaterium.
The ribosomal particles and nucleic acid components of Bacillus megaterium log phase cells and spores were isolated and compared. Analysis of the total RNA indicated that 23 S, 16 S, and 4 S components were present, in the same relative proportions in both cases. Soluble RNA was 19% of vegetative cell RNA and 21% of spore RNA. Particles sedimenting at values greater than 100 S and sensitive to ...
متن کاملBiochemical Studies of Bacterial Sporulation and Germination XXII. ENERGY METABOLISM IN EARLY STAGES OF GERMINATION OF BACILLUS MEGATERIUM
Dormant spores of Bacillus megaferium contain DPN+, TPN+, and FAD at levels comparable to those in log phase vegetative cells, but little or no reduced pyridine nucleotides are present. The levels of free nucleotides, the most abundant of which are the adenine nucleotides, are also similar in spores and cells. In cells, however, 80% of the adenine nucleotide pool is ATP, whereas in spores it is...
