402880 [NCBI]

Taxonomic lineage

Archaea › Euryarchaeota › Methanococci › Methanococcales › Methanococcaceae › Methanococcus

Protein attributes

Sequence length	288 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the condensation of ATP and 5-phosphoribose 1-diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity By similarity. HAMAP MF_00079
Catalytic activity	1-(5-phospho-D-ribosyl)-ATP + diphosphate = ATP + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_00079
Cofactor	Magnesium By similarity. HAMAP MF_00079
Enzyme regulation	Feedback inhibited by histidine By similarity. HAMAP MF_00079
Pathway	Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/9. HAMAP MF_00079
Subcellular location	Cytoplasm By similarity HAMAP MF_00079.
Sequence similarities	Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
