Cyclic di-GMP phosphodiesterase PA4781

UniProtKB accession:  Q9HV27

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Phosphodiesterase (PDE) that catalyzes the hydrolysis of cyclic diguanylate (c-di-GMP) to GMP (PubMed:19170727, PubMed:24066157). Hydrolyzes c-di-GMP to GMP in a two-step reaction, via the linear intermediate 5'-phosphoguanylyl(3'->5')guanosine (pGpG). In vitro, can use pGpG as an alternative substrate and hydrolyze it into GMP (PubMed:24066157). Acts in regulation of motility, synthesis of virulence determinants and biofilm architecture (PubMed:19170727). May act preferentially as a pGpG binding protein (PubMed:24066157).
