Function
function
IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
Catalytic activity
- 5-[(5-phospho-1-deoxy-D-ribulos-1-ylimino)methylamino]-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide + L-glutamine = D-erythro-1-(imidazol-4-yl)glycerol 3-phosphate + 5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide + L-glutamate + H+
Pathway
Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 5/9.
