Organism

Brucella abortus (strain 2308) [Complete proteome] [HAMAP]

Taxonomic identifier

359391 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Brucellaceae › Brucella

Protein attributes

Sequence length	750 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Functions as a (p)ppGpp synthetase. 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. Plays a role in adaptation of Brucella to its intracellular host environment By similarity.
Catalytic activity	ATP + GTP = AMP + guanosine 3'-diphosphate 5'-triphosphate.
Sequence similarities	Belongs to the relA/spoT family. Contains 1 ACT domain. Contains 1 HD domain.
