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. {ECO:0000255|HAMAP-Rule:MF_00272}.
CC   -!- COFACTOR:
CC       Name=(R)-lipoate; Xref=ChEBI:CHEBI:83088;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00272};
CC       Note=Binds 1 lipoyl cofactor covalently. {ECO:0000255|HAMAP-
CC       Rule:MF_00272};
CC   -!- SUBUNIT: The glycine cleavage system is composed of four proteins: P,
CC       T, L and H. {ECO:0000255|HAMAP-Rule:MF_00272}.
CC   -!- SIMILARITY: Belongs to the GcvH family. {ECO:0000255|HAMAP-
CC       Rule:MF_00272}.
