CC -!- FUNCTION: Converts glutamate to gamma-aminobutyrate (GABA), consuming
CC one intracellular proton in the reaction. The gad system helps to
CC maintain a near-neutral intracellular pH when cells are exposed to
CC extremely acidic conditions. The ability to survive transit through the
CC acidic conditions of the stomach is essential for successful
CC colonization of the mammalian host by commensal and pathogenic
CC bacteria. {ECO:0000256|ARBA:ARBA00024984}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-glutamate = 4-aminobutanoate + CO2;
CC Xref=Rhea:RHEA:17785, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:59888; EC=4.1.1.15;
CC Evidence={ECO:0000256|ARBA:ARBA00000018,
CC ECO:0000256|RuleBase:RU361171};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|PIRSR:PIRSR602129-50, ECO:0000256|RuleBase:RU000382};
CC -!- SIMILARITY: Belongs to the group II decarboxylase family.
CC {ECO:0000256|RuleBase:RU000382}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
