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.
