Unique ID
D005722
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D005722
Annotation
do not confuse with GAMMA-GLUTAMYLTRANSFERASE
Scope Note
An enzyme that catalyzes the synthesis of pyroglutamate from a gamma-glutamyl-amino acid, also releasing the free amino acid. The enzyme acts on derivatives of glutamate, 2-aminobutyrate, alanine and glycine. The enzyme has been proposed to have a role in a gamma-glutamyl cycle for amino acid transport into cells in the intestines. EC 2.3.2.4.
