General annotation (Comments)

Function

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.

Catalytic activity

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

Pathway

Purine metabolism; ppGpp biosynthesis; ppGpp from GTP: step 1/2.

Sequence similarities

Belongs to the RelA/SpoT family.

Contains 1 ACT domain.
