Active Site
Activity Regulation ACTIVITY REGULATION: Activity repressed by anti-sigma-G factor Gin (csfB) and Lon protease during the early stages of forespore development (PubMed:17921305). When both Gin and sigma-G are expressed in E.coli Gin inhibits sigma-G activity, strongly suggesting Gin inhibits by direct physical interaction (PubMed:19497328). {ECO:0000269|PubMed:17921305, ECO:0000269|PubMed:19497328}.

EC Number
Enzyme Function FUNCTION: Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released (PubMed:18208527). This sigma factor is responsible for the expression of sporulation specific genes in the forespore (PubMed:18208527). {ECO:0000269|PubMed:18208527}.
