Regulation 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...
متن کاملThe ftsH gene of Bacillus subtilis is involved in major cellular processes such as sporulation, stress adaptation and secretion.
The ftsH gene of Bacillus subtilis has been identified as a general stress gene which is transiently induced after thermal or osmotic upshift. The FtsH protein exhibits 70.1% homology to FtsH of Escherichia coli which constitutes an essential ATP- and Zn(2+)-dependent protease anchored in the cytoplasmic membrane via two N-terminal transmembrane domains. This paper describes the isolation and f...
متن کاملRequirement for the cell division protein DivIB in polar cell division and engulfment during sporulation in Bacillus subtilis.
During spore formation in Bacillus subtilis, cell division occurs at the cell pole and is believed to require essentially the same division machinery as vegetative division. Intriguingly, although the cell division protein DivIB is not required for vegetative division at low temperatures, it is essential for efficient sporulation under these conditions. We show here that at low temperatures in ...
متن کاملThe FtsH protein accumulates at the septum of Bacillus subtilis during cell division and sporulation.
The ftsH gene encodes an ATP- and Zn(2+)-dependent metalloprotease which is anchored to the cytoplasmic membrane via two transmembrane segments in such a way that the very short amino- and the long carboxy termini are exposed to the cytoplasm. Deletion of the ftsH gene in Bacillus subtilis results in a pleiotropic phenotype such as filamentous growth. This observation prompted us to ask whether...
متن کاملIdentification and characterization of sporulation gene spoVS from Bacillus subtilis.
We report the identification and characterization of an additional sporulation gene from Bacillus subtilis called spoVS, which is induced early in sporulation under the control of sigma H. We show that spoVS is an 86-codon-long open reading frame and is capable of encoding a protein of 8,796 Da which exhibits little similarity to other proteins in the databases. Null mutations in spoVS have two...
