CC   -!- FUNCTION: Catalyzes the pyridoxal-dependent decarboxylation of
CC       glutamate to produce 4-aminobutanoate. Has weak activity with
CC       aspartate, but cannot complement an E. coli panD deletion mutant.
CC       {ECO:0000269|PubMed:28446608}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + L-glutamate = 4-aminobutanoate + CO2;

CC         Evidence={ECO:0000269|PubMed:28446608};
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=61.7 mM for glutamate (at 37 degrees Celsius)
CC         {ECO:0000269|PubMed:28446608};
CC         Note=kcat is 0.055 sec(-1) at 37 degrees Celsius.
CC         {ECO:0000269|PubMed:28446608};
CC   -!- SIMILARITY: Belongs to the group II decarboxylase family.
CC       {ECO:0000305}.
