Glycine cleavage system H-protein (IPR002930)

Short name: GCV_H

Overlapping homologous superfamilies

Family relationships


This is a family of glycine cleavage H-proteins, part of the glycine cleavage system (GCS) found in bacteria, archaea, and the mitochondria of eukaryotes. GCS is a multienzyme complex consisting of 4 different components (P-, H-, T- and L-proteins) which catalyzes the oxidative cleavage of glycine [PMID: 11286922]. The H-protein shuttles the methylamine group of glycine from the P-protein (glycine dehydrogenase) to the T-protein (aminomethyltransferase) via a lipoyl group, attached to a completely conserved lysine residue [PMID: 8197146].
