Eb. Simpson et al., TRANSCRIPTIONAL CONTROL OF DACB, WHICH ENCODES A MAJOR SPORULATION-SPECIFIC PENICILLIN-BINDING PROTEIN, Journal of bacteriology, 176(24), 1994, pp. 7767-7769
Sporulation-specific sigma factor E (sigma(E)) of Bacillus subtilis is
both necessary and sufficient for transcription of the dacB gene, whi
ch encodes penicillin-binding protein 5(not asymptotic to). Evidence i
n support of this conclusion was obtained by primer extension analysis
of dacB transcripts and the induction of active sigma(E) with subsequ
ent synthesis of PBP 5(not asymptotic to) in vegetative cells.
