metabolism |
the enzyme is one of the four components that form the glycine cleavage complex (GCS), essential for the synthesis of C1 (one-carbon units) for cell metabolism, by the oxidative cleavage of glycine. The glycine cleavage complex (GCS), in cooperation with GCA (serine hydroxymethyltransferase) regulates the endogenous levels of glycine and C1 units in the cell. This system comprises four loosely associated proteins, namely GcvP (a pyridoxal phosphate-containing protein), GcvH (a protein that carries aminomethyl intermediate), GcvT (protein required for tetrahydrofolate-dependent reaction) and GcvL (a lipoamide dehydrogenase). GcvP decarboxylates glycine and relocates the remaining methylamine moiety to the lipoyl group of GcvH |
