CC -!- FUNCTION: The glycine cleavage system catalyzes the degradation of
CC glycine. The P protein binds the alpha-amino group of glycine through
CC its pyridoxal phosphate cofactor; CO(2) is released and the remaining
CC methylamine moiety is then transferred to the lipoamide cofactor of the
CC H protein. {ECO:0000256|ARBA:ARBA00003788, ECO:0000256|HAMAP-
CC Rule:MF_00713}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glycine + H(+) + N(6)-[(R)-lipoyl]-L-lysyl-[glycine-cleavage
CC complex H protein] = CO2 + N(6)-[(R)-S(8)-aminomethyldihydrolipoyl]-
CC L-lysyl-[glycine-cleavage complex H protein]; Xref=Rhea:RHEA:24304,

CC Evidence={ECO:0000256|ARBA:ARBA00043839, ECO:0000256|HAMAP-
CC Rule:MF_00713};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00713};
CC -!- SUBUNIT: The glycine cleavage system is composed of four proteins: P,
CC T, L and H. In this organism, the P 'protein' is a heterodimer of two
CC subunits. {ECO:0000256|HAMAP-Rule:MF_00713}.
CC -!- SIMILARITY: Belongs to the GcvP family. C-terminal subunit subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00713}.
