CC   -!- FUNCTION: Converts internalized glutamate to GABA and increases
CC       the internal pH. Involved in glutamate-dependent acid resistance
CC       (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY: L-glutamate = 4-aminobutanoate + CO(2).
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250};
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 4.7. Active at acidic pHs but inactive in the
CC         neutral pH range.;
CC       Temperature dependence:
CC         Active up to 70 degrees Celsius at pH 4.1.;
CC   -!- SIMILARITY: Belongs to the group II decarboxylase family.
CC       {ECO:0000305}.
