Signal recognition particle (docking protein); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC).

Chromosome condensation and segregation factor; Participates in chromosomal partition during cell division. May act via the formation of a condensin-like complex containing Smc and ScpA that pull DNA away from mid-cell into both cell halves; Belongs to the ScpB family.

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.

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.

Cell-division initiation protein; May act as a pilot protein, directing MinCD to the polar septation sites or by inhibiting MinCD at the midcell site of division. Required for polar localization of the chromosome during sporulation.

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.

Ribonuclease III; Digests double-stranded RNA. Involved in the processing of ribosomal RNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Also processes pre-scRNA (the precursor of the signal recognition particle RNA). Probably also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Probably processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.

Protein kinase; Protein kinase that is responsible for triggering spore germination in response to muropeptides, signaling bacteria to exit dormancy. PrkC is thus a germination receptor that binds peptidoglycan fragments containing m-Dpm (meso-diaminopimelate), which act as spore germinants. Autophosphorylates and phosphorylates EF-G (elongation factor G, fusA); the latter modification is likely necessary for germination in response to peptidoglycan. Another group did not detect phosphorylation of EF-G. PrkC is a substrate in vitro of the cotranscribed phosphatase PrpC, which suggests [...]

Topological determinant of cell division; The main function of the Min system is to promote the disassembly of the cytokinetic ring after cell division, thereby ensuring that division occurs only once per cell cycle. MinJ acts as a bridge between DivIVA and MinD. May modulate activity and localization of MinD and MinC through direct interaction with MinD.
