General annotation (Comments)
| Function | 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. Probably autophosphorylates and phosphorylates FusA (EF-G, elongation factor G); the latter modification is likely necessary for germination in response to peptidoglycan. Ref.4 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Spore core membrane; Single-pass type II membrane protein. Note: Is associated with the inner membrane of the spore By similarity. |
| Domain | The C-terminal extracellular domain containing the PASTA repeats binds peptidoglycan By similarity. |
| Disruption phenotype | Spores lacking this gene fail to germinate in the presence of peptidoglycan fragments. Ref.4 |
| Miscellaneous | Ref.4 shows that peptidoglycan fragments serve as a novel mechanism of interspecies bacterial signaling that likely indicates the presence of growing bacteria and thus serve as a signal for dormant cells that growth-promoting conditions exist. |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 3 PASTA domains. Contains 1 protein kinase domain. |
