OC Bacteria; Proteobacteria; Gammaproteobacteria; Aeromonadales; OC Aeromonadaceae; Aeromonas. OX NCBI_TaxID=380703; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=16980456; DOI=10.1128/JB.00621-06; RA Seshadri R., Joseph S.W., Chopra A.K., Sha J., Shaw J., Graf J., RA Haft D.H., Wu M., Ren Q., Rosovitz M.J., Madupu R., Tallon L., Kim M., RA Jin S., Vuong H., Stine O.C., Ali A., Horneman A.J., Heidelberg J.F.; RT "Genome sequence of Aeromonas hydrophila ATCC 7966T: jack of all RT trades."; RL J. Bacteriol. 188:8272-8282(2006). CC -!- CATALYTIC ACTIVITY: 10-formyltetrahydrofolate + 5-amino-1-(5- CC phospho-D-ribosyl)imidazole-4-carboxamide = tetrahydrofolate + 5- CC formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide. CC -!- CATALYTIC ACTIVITY: IMP + H(2)O = 5-formamido-1-(5-phospho-D- CC ribosyl)imidazole-4-carboxamide. CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; CC 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5- CC amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide (10-formyl CC THF route): step 1/1. CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via de novo pathway; CC IMP from 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4- CC carboxamide: step 1/1. CC -!- DOMAIN: The IMP cyclohydrolase activity resides in the N-terminal CC region (By similarity). CC -!- SIMILARITY: Belongs to the purH family.
