Protein

Glycine dehydrogenase (decarboxylating), mitochondrial

Gene

GLDC

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

The glycine cleavage system catalyzes the degradation of glycine. The P protein (GLDC) binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO2 is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein (GCSH).3 Publications

Catalytic activityi

Glycine + [glycine-cleavage complex H protein]-N6-lipoyl-L-lysine = [glycine-cleavage complex H protein]-S-aminomethyl-N6-dihydrolipoyl-L-lysine + CO2.3 Publications

Cofactori

pyridoxal 5'-phosphateBy similarity

Enzyme regulationi

Stimulated by lipoic acid. Inhibited in presence of methylamine (By similarity).By similarity
