EC 2.3.1.204

Accepted name: octanoyl-[GcvH]:protein N-octanoyltransferase

Reaction: [glycine cleavage system H]-N6-octanoyl-L-lysine + a [lipoyl-carrier protein] = glycine cleavage system H + a [lipoyl-carrier protein]-N6-octanoyl-L-lysine

Glossary: GcvH = glycine cleavage system H]

Other name(s): LipL; octanoyl-[GcvH]:E2 amidotransferase; ywfL (gene name)

Systematic name: [glycine cleavage system H]-N6-octanoyl-L-lysine:[lipoyl-carrier protein]-N6-L-lysine octanoyltransferase

Comments: In the bacterium Bacillus subtilis it has been shown that the enzyme catalyses the amidotransfer of the octanoyl moiety from [glycine cleavage system H]-N6-octanoyl-L-lysine (i.e. octanoyl-GcvH) to the E2 subunit (dihydrolipoamide acetyltransferase) of pyruvate dehydrogenase.
