CC -!- FUNCTION: Catalyzes the conversion of inosine 5'-phosphate (IMP) to
CC xanthosine 5'-phosphate (XMP), the first committed and rate-limiting
CC step in the de novo synthesis of guanine nucleotides, and therefore
CC plays an important role in the regulation of cell growth.
CC {ECO:0000256|HAMAP-Rule:MF_03156}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + IMP + NAD(+) = H(+) + NADH + XMP; Xref=Rhea:RHEA:11708,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57464,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:58053;
CC EC=1.1.1.205; Evidence={ECO:0000256|ARBA:ARBA00024264,
CC ECO:0000256|HAMAP-Rule:MF_03156, ECO:0000256|RuleBase:RU003928};
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000256|ARBA:ARBA00001958,
CC ECO:0000256|HAMAP-Rule:MF_03156};
CC -!- ACTIVITY REGULATION: Mycophenolic acid (MPA) is a non-competitive
CC inhibitor that prevents formation of the closed enzyme conformation by
CC binding to the same site as the amobile flap. In contrast, mizoribine
CC monophosphate (MZP) is a competitive inhibitor that induces the closed
CC conformation. MPA is a potent inhibitor of mammalian IMPDHs but a poor
CC inhibitor of the bacterial enzymes. MZP is a more potent inhibitor of
CC bacterial IMPDH. {ECO:0000256|HAMAP-Rule:MF_03156}.
CC -!- PATHWAY: Purine metabolism; XMP biosynthesis via de novo pathway; XMP
CC from IMP: step 1/1. {ECO:0000256|HAMAP-Rule:MF_03156,
CC ECO:0000256|RuleBase:RU003928}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_03156}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03156}.
CC -!- SIMILARITY: Belongs to the IMPDH/GMPR family.
CC {ECO:0000256|ARBA:ARBA00005502, ECO:0000256|HAMAP-Rule:MF_03156,
CC ECO:0000256|RuleBase:RU003927}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03156}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
