molecular function
    GO:0003937    IMP cyclohydrolase activity    Catalysis of the reaction: IMP + H2O = 5-formamido-1-(5-phosphoribosyl)imidazole-4-carboxamide.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
    GO:0006189    'de novo' IMP biosynthetic process    The chemical reactions and pathways resulting in the formation of IMP, inosine monophosphate, by the stepwise assembly of a purine ring on ribose 5-phosphate.
    GO:0006188    IMP biosynthetic process    The chemical reactions and pathways resulting in the formation of IMP, inosine monophosphate.
    GO:0006164    purine nucleotide biosynthetic process    The chemical reactions and pathways resulting in the formation of a purine nucleotide, a compound consisting of nucleoside (a purine base linked to a deoxyribose or ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar.
