EC 4.1.1.15

Accepted name: glutamate decarboxylase

Reaction: L-glutamate = 4-aminobutanoate + CO2

Glossary: 4-aminobutanoate = γ-aminobutyrate = GABA

Other name(s): L-glutamic acid decarboxylase; L-glutamic decarboxylase; cysteic acid decarboxylase; L-glutamate α-decarboxylase; aspartate 1-decarboxylase; aspartic α-decarboxylase; L-aspartate-α-decarboxylase; γ-glutamate decarboxylase; L-glutamate 1-carboxy-lyase

Systematic name: L-glutamate 1-carboxy-lyase (4-aminobutanoate-forming)

Comments: A pyridoxal-phosphate protein. The brain enzyme also acts on L-cysteate, 3-sulfino-L-alanine and L-aspartate.
