RC STRAIN=ATCC BAA-645; RA Becker E.A., Seitzer P., Tritt A., Larsen D., Yao A., Wu D., RA Darling A., Eisen J.A., Facciotti M.T.; RL Submitted (NOV-2012) to the EMBL/GenBank/DDBJ databases. CC -!- CATALYTIC ACTIVITY: 1-(5-phospho-beta-D-ribosyl)-AMP + H(2)O = 1- CC (5-phospho-beta-D-ribosyl)-5-((5-phospho-beta-D- CC ribosylamino)methylideneamino)imidazole-4-carboxamide. CC -!- PATHWAY: Amino-acid biosynthesis; L-histidine biosynthesis; L- CC histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 3/9. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the PRA-CH family. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data.
