Reaction: [glycine cleavage system H]-N6-lipoyl-L-lysine + a [lipoyl-carrier protein] = glycine cleavage system H + a [lipoyl-carrier protein]-N6-lipoyl-L-lysine
Glossary: lipoic acid = 5-[(3R)-1,2-dithiolan-3-yl]pentanoic acid
Other name(s): LipL (gene name, ambiguous)
Systematic name: [glycine cleavage system H]-N6-lipoyl-L-lysine:[lipoyl-carrier protein]-N6-L-lysine lipoyltransferase
Comments: In the bacterium Listeria monocytogenes the enzyme takes part in a pathway for scavenging of lipoic acid. The enzyme is bound to 2-oxo-acid dehydrogenases such as the pyruvate dehydrogenase complex, where it transfers the lipoyl moiety from lipoyl-[glycine cleavage system H] to the E2 subunits of the complexes.
