Enzyme Commission Summary:
A pyridoxal-phosphate protein. A component of the glycine cleavage system, which is composed of four components that only loosely associate: the P protein (EC 184.108.40.206), the T protein (EC 220.127.116.11), the L protein (EC 18.104.22.168) and the lipoyl-bearing H protein [Nesbitt05]. Previously known as glycine synthase.
Instance reaction of [a [lipoyl-carrier protein] N6-dihydrolipoyl-L-lysine + NAD+ → a [lipoyl-carrier protein] N6-lipoyl-L-lysine + NADH + H+] (22.214.171.124):
i2: a [glycine-cleavage complex H protein] N6-dihydrolipoyl-L-lysine + NAD+ ↔ a [glycine-cleavage complex H protein] N6-lipoyl-L-lysine + NADH + H+ (126.96.36.199)
