CC   -!- FUNCTION: Catalyzes the production of GABA. The calmodulin-binding is
CC       calcium-dependent and it is proposed that this may, directly or
CC       indirectly, form a calcium regulated control of GABA biosynthesis (By
CC       similarity). {ECO:0000250}.
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   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250};
CC   -!- SUBUNIT: Homohexamer. Interacts with calmodulin (By similarity).
CC       {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed at low levels in siliques.
CC       {ECO:0000269|PubMed:18077464}.
CC   -!- SIMILARITY: Belongs to the group II decarboxylase family.
CC       {ECO:0000305}.
