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. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp (By similarity).By similarity

Catalytic activityi

ATP + GTP = AMP + guanosine 3'-diphosphate 5'-triphosphate.

Pathwayi: ppGpp biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes ppGpp from GTP.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. GTP pyrophosphokinase (relA)
  2. no protein annotated in this organism
This subpathway is part of the pathway ppGpp biosynthesis, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes ppGpp from GTP, the pathway ppGpp biosynthesis and in Purine metabolism.
