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.
CATALYTIC ACTIVITY: IMP + H₂O = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide.
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 .
PATHWAY: 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).
SIMILARITY: Belongs to the purH family.
