RA   Michalowski C.B., Bohnert H.J.;
RL   Submitted (NOV-1996) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: The glycine cleavage system catalyzes the degradation of
CC       glycine. The H protein shuttles the methylamine group of glycine from
CC       the P protein to the T protein.
CC   -!- COFACTOR:
CC       Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088;
CC       Note=Binds 1 lipoyl cofactor covalently.;
CC   -!- SUBUNIT: The glycine cleavage system is composed of four proteins: P,
CC       T, L and H.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion.
CC   -!- SIMILARITY: Belongs to the GcvH family. {ECO:0000305}.
