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.
