Protein attributes

Sequence length	494 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the production of GABA. The calmodulin-binding is calcium-dependent and it is proposed that this may, directly or indirectly, form a calcium regulated control of GABA biosynthesis By similarity.
Catalytic activity	L-glutamate = 4-aminobutanoate + CO2.
Cofactor	Pyridoxal phosphate.
Sequence similarities	Belongs to the group II decarboxylase family.
