Phosphoglucosamine mutase; Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate (By similarity). Glucosamine-1-phosphate is used for cell wall biosynthesis (Probable); Belongs to the phosphohexose mutase family.

Phosphodiesterase acting on cyclic dinucleotides; Has phosphodiesterase (PDE) activity against cyclic-di-AMP (c-di-AMP) and to a much lesser extent against cyclic-di-GMP (c-di-GMP) in the DHH/DHHA1 domains. Also has ATPase activity, probably via the GGDEF domain. Overexpression leads to increased sensitivity to methyl methanesulfonate (MMS) and H(2)O(2). Overexpression leads to extreme sensitivity to the beta-lactam antibiotic cefuroxime (CEF), probably dependent on PDE activity. May monitor cellular heme or NO levels. In B.subtilis c-di-AMP is a second messenger that mediates growth, [...]

Putative membrane associate hydrolase; Probably has phosphodiesterase (PDE) activity against cyclic- di-AMP (c-di-AMP); may be the major c-di-AMP PDE in the cell. In B.subtilis c-di-AMP is a second messenger that mediates growth, DNA repair and cell wall homeostasis; it is toxic when present in excess.

Putative enzyme with DAC domain; One of 3 paralogous diadenylate cyclases (DAC) in this bacteria, catalyzing the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP) (Probable). Upon expression in E.coli leads to c-di- AMP synthesis. Overexpression of the hyperactive mutant (L44F) in the absence of c-di-AMP phosphodiesterase GdpP leads to growth defects in log phase (long curly cell filaments) that disappear upon sporulation; spore formation is normal, showing sporulation is insensitive to the excess c-di-AMP. In B.subtilis c-di-AMP is a second messenger that mediates growth, [...]

anti-sigma(W) factor; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, PrsW) , then within the membrane itself (site-2 protease, S2P [...]

Primosomal replication factor Y (primosomal protein N'); Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily.

RNA polymerase ECF(extracytoplasmic function)-type sigma factor W; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma-W controls genes involved in response to cell envelope stress such as antimicrobial peptides , alkaline pH , transport processes and detoxification.

Penicillin-binding protein 2B; Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. PBP-2B is required for vegetative cell division and sporulation septation. Beta-lactamase inactivates the PBPs by acylating an essential serine residue in the active site of these proteins, thereby interrupting normal cell wall synthesis; Belongs to the transpeptidase family.

Cell-division initiation protein; Cell division protein that may be involved in stabilizing or promoting the assembly of the division complex. Plays an essential role in division at high temperatures, maybe by protecting FtsL from degradation or by promoting formation of the FtsL-DivIC complex. May modulate the transpeptidase activity of PBP-2B. Also required for efficient sporulation at all temperatures. Could be directly involved in the engulfment process or be required to form a sporulation septum competent for engulfment. Influences the Spo0J/Soj system of chromosome segregation. B [...]
