Methionine sulfoxide and specific inhibition of sporulation in Bacillus subtilis.
Methionine sulfoxide has been shown to be a specific antagonist of glutamic acid in the conversion of glutamic acid to glutamine by Waelsch, Owades, Miller, and Borek (J. Biol. Chem., 166, 273, 1946) in growth inhibition studies with Lactobacillus arabinosus. Elliot and Gale (Nature, 161, 129, 1948) using cell-free extracts of Staphylococcus aureus have demonstrated that methionine sulfoxide in...
متن کاملPostexponential regulation of sin operon expression in Bacillus subtilis.
The expression of many gene products required during the early stages of Bacillus subtilis sporulation is regulated by sinIR operon proteins. Transcription of sinIR from the P1 promoter is induced at the end of exponential growth. In vivo transcription studies suggest that P1 induction is repressed by the transition-state regulatory protein Hpr and is induced by the phosphorylated form of Spo0A...
متن کاملEvolution of the transcription complex during sporulation of Bacillus subtilis.
Ribonucleic acid polymerase activity in partially purified extract of cells of Bacillus subtilis harvested at different times (t-1, to, t1, and t2) was studied by zone centrifugation. During the course of sporulation, vegetative sigma-factor activity decreased and the transcription complex lost some of its affinity for active sigma factor. The complex underwent a two-stage change in sedimentati...
متن کاملForespore-specific transcription of the lonB gene during sporulation in Bacillus subtilis.
The Bacillus subtilis genome encodes two members of the Lon family of prokaryotic ATP-dependent proteases. One, LonA, is produced in response to temperature, osmotic, and oxidative stress and has also been implicated in preventing sigma(G) activity under nonsporulation conditions. The second is encoded by the lonB gene, which resides immediately upstream from lonA. Here we report that transcrip...
متن کاملRegulation of transcription of the cell division gene ftsA during sporulation of Bacillus subtilis.
Three distinct 5' ends of ftsA mRNA were identified by S1 mapping and by primer extension analysis. These are thought to represent three transcription start sites. The transcripts from the downstream and upstream sites were detected throughout growth. The transcript from the middle site was not detected during exponential growth but was detected within 30 min of the start of sporulation, when i...
