General annotation (Comments)

Catalytic activity

1-(5-phospho-beta-D-ribosyl)-5-((5-phospho-beta-D-ribosylamino)methylideneamino)imidazole-4-carboxamide = 5-((5-phospho-1-deoxy-D-ribulos-1-ylamino)methylideneamino)-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide. HAMAP-Rule MF_01014

Pathway

Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 4/9. HAMAP-Rule MF_01014

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01014.

Sequence similarities

Belongs to the HisA/HisF family.

Sequence caution

The sequence ABB25745.1 differs from that shown. Reason: Erroneous initiation.
