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:0000255|HAMAP-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   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|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:0000255|HAMAP-Rule:MF_00713}.
CC   -!- SIMILARITY: Belongs to the GcvP family. C-terminal subunit subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00713}.
