Restricted transcription from sigma H or phosphorylated spo0A dependent promoters in the temperature-sensitive secA341 mutant of Bacillus subtilis.

Bioscience, biotechnology, and biochemistry - 1 Sept 1998

Abstract excerpt

The temperature-sensitive secA341 mutation of Bacillus subtilis affects sporulation and sporulation-associated events as well as protein secretion and cell septation. With lacZ or bgaB fusion genes, we examined the expression of the early sporulation genes in the mutant strain. Transcriptional expression of delta H dependent kinA, spo0A (Ps), phrC, spoVG, and citG (p2) genes was blocked by the secA341 mutation at...
