General annotation (Comments)

Catalytic activity

10-formyltetrahydrofolate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide = tetrahydrofolate + 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide. HAMAP MF_00139

IMP + H2O = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide. HAMAP MF_00139

Pathway

Purine metabolism; IMP biosynthesis via de novo pathway; 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide from 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide (10-formyl THF route): step 1/1. HAMAP MF_00139

Purine metabolism; IMP biosynthesis via de novo pathway; IMP from 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide: step 1/1.

Domain

The IMP cyclohydrolase activity resides in the N-terminal region By similarity. HAMAP MF_00139
