DnaA can inhibit its own gene expression as well as that of other genes. (446 aa)
yaaHSpore peptidoglycan hydrolase; N-acetylglucosaminidase involved in cortex peptidoglycan degradation during germination. Cleaves only partially degraded spore peptidoglycans. Recognizes muramic acid delta-lactam residues specific to spore peptidoglycans. (427 aa)
ctsRTranscriptional regulator; Controls the expression of the cellular protein quality control genes clpC, clpE and clpP, as well as mcsA and mcsB.
