Protein
Guanosine-3',5'-bis(diphosphate) 3'-pyrophosphohydrolase
Gene
spoT, VC_2710
Organism
Vibrio cholerae serotype O1 (strain ATCC 39315 / El Tor Inaba N16961)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance By similarity.

Catalytic activityi

Guanosine 3',5'-bis(diphosphate) + H2O = guanosine 5'-diphosphate + diphosphate.

Cofactori

Manganese By similarity.
