Protein
Cyclic di-GMP phosphodiesterase PA4781
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Function
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).
