CC -!- FUNCTION: Response regulator that is part of a signal transduction
CC pathway controlling cell differentiation in the swarmer-to-stalked cell
CC transition. {ECO:0000250}.
CC -!- FUNCTION: Catalyzes the condensation of two GTP molecules to the cyclic
CC dinucleotide di-GMP (c-di-GMP), which acts as a secondary messenger.
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 GTP = 3',3'-c-di-GMP + 2 diphosphate; Xref=Rhea:RHEA:24898,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:58805; EC=2.7.7.65;
CC -!- ACTIVITY REGULATION: Allosterically inhibited by the product c-di-GMP.
CC {ECO:0000250}.
CC -!- PATHWAY: Purine metabolism; 3',5'-cyclic di-GMP biosynthesis.
CC -!- SUBUNIT: Homodimer. Inactive monomer in solution (By similarity).
CC {ECO:0000250}.
CC -!- INTERACTION:
CC Q9A5I5; Q03228: divJ; NbExp=3; IntAct=EBI-1784732, EBI-1785038;
CC Q9A5I5; P37894: pleC; NbExp=4; IntAct=EBI-1784732, EBI-1784742;
CC Q9A5I5; Q9A5I5: pleD; NbExp=4; IntAct=EBI-1784732, EBI-1784732;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Note=Phosphorylated PleD
CC localizes to the differentiating pole.
CC -!- DOMAIN: Activated by phosphorylation at the first response regulatory
CC domain, which induces dimerization mediated by the two response
CC regulatory domains and allows the two substrate-binding sites to
CC approach each other and the condensation reaction to occur (Probable).
CC The diguanylate cyclase activity is harbored by the GGDEF domain (By
CC similarity). {ECO:0000250, ECO:0000305}.
CC -!- PTM: Phosphorylated by PleC and DivJ. Phosphorylation stimulates
CC cyclase activity (By similarity). {ECO:0000250}.
