Accepted name:
glycine dehydrogenase (aminomethyl-transferring)
Other names:
glycine decarboxylase
glycine-cleavage complex
glycine:lipoylprotein oxidoreductase (decarboxylating and acceptor-aminomethylating)
protein P1
glycine cleavage system P-protein

Systematic name:

A pyridoxal-phosphate protein. A component of the glycine cleavage system, which is composed of four components that only loosely associate: the P protein (EC, the T protein (EC, aminomethyltransferase), the L protein (EC, dihydrolipoyl dehydrogenase) and the lipoyl-bearing H protein [3]. Previously known as glycine synthase.
