cotB | Spore coat protein (outer); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type s: structure. (380 aa) | ||||
cotH | Spore coat protein (inner); Involved in the assembly of several proteins in the inner and outer layer of the spore coat. Stabilizes CotC and CotU in the mother cell compartment of sporulating cells and promotes the assembly of both early and late forms of CotC-related polypeptides on the spore surface. Belongs to the CotH family. (362 aa) | ||||
cotG | Spore morphogenetic protein; May be a morphogenetic protein that is required for the incorporation of protein CotB into the spore coat. (195 aa) | ||||
spoIIID | Transcriptional regulator; This protein regulates the transcription of sigK, which encodes mother cell chamber RNA polymerase sigma-factor (sigma K). (93 aa) | ||||
spoIIQ | Forespore protein required for alternative engulfment; Involved in forespore engulfment and required for anchoring membrane proteins on the forespore side of the septal membrane. Forms a channel with SpoIIIAH that is open on the forespore end and closed (or gated) on the mother cell end. This allows sigma-E-directed gene expression in the mother-cell compartment of the sporangium to trigger the activation of sigma-G forespore-specific gene expression by a pathway of intercellular signaling. (283 aa) | ||||
rapB | Response regulator aspartate phosphatase; Prevents sporulation by dephosphorylating Spo0F. (377 aa) | ||||
spoIID | Autolysin required for complete dissolution of the asymmetric septum (stage II sporulation); May act at the level of sigma-G activity or its stability. SpoIID is probably required for engulfment. (343 aa) | ||||
spoIIR | pro-sigma(E) endopeptidase (stage II sporulation); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (224 aa) | ||||
racA | Chromosome-anchoring protein RacA; Required for the formation of axial filaments and for anchoring the origin regions at the cell poles in sporulating cells, thus ensuring proper chromosome segregation in the prespore. Binds in a dispersed manner throughout the chromosome but preferentially to sites clustered in the origin portion of the chromosome, causing condensation of the chromosome and its remodeling into an elongated, anchored structure; Belongs to the RacA family. (184 aa) | ||||
fbaA | Fructose-1,6-bisphosphate aldolase; Catalyzes the aldol condensation of dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with glyceraldehyde 3-phosphate (G3P) to form fructose 1,6-bisphosphate (FBP) in gluconeogenesis and the reverse reaction in glycolysis. (285 aa) | ||||
spo0F | Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation. (124 aa) | ||||
rsfA | Prespore-specific regulatory gene; Seems to improve the efficiency of sporulation by fine-tuning the expression of genes in the sigma F regulon, particularly the timing of their expression. Negatively regulates spoIIR and its own synthesis. (258 aa) | ||||
gerQ | Inner spore coat protein; Essential for the localization of CwlJ in the spore coat and for spore germination triggered by calcium and dipicolinic acid (DPA). Its assembly into the spore coat is dependent on the coat morphogenetic proteins CotE and SpoIVA. (181 aa) | ||||
katE | Catalase 2; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. Involved in sporulation. (686 aa) | ||||
cdnD | 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, [...] (659 aa) | ||||
cotF | Spore coat protein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type s: structure. (160 aa) | ||||
parB | Site-specific DNA-binding protein; Required for the initiation of sporulation and for normal chromosome segregation. Antagonizes sporulation inhibition by Soj. It probably interacts with a specific DNA site and other proteins involved in partitioning and cell division, and antagonizes Soj in response to cell cycle events related to chromosome partitioning. (282 aa) | ||||
parA | Chromosome partitioning protein; Inhibits the initiation of sporulation, Spo0J antagonizes this inhibition. Soj ultimately inhibits the activation (phosphorylation) of Spo0A; Belongs to the ParA family. (253 aa) |
