Data 5:170203-170203(2018). CC -!- FUNCTION: Catalyzes the radical-mediated insertion of two sulfur CC atoms into the C-6 and C-8 positions of the octanoyl moiety bound CC to the lipoyl domains of lipoate-dependent enzymes, thereby CC converting the octanoylated domains into lipoylated derivatives. CC {ECO:0000256|HAMAP-Rule:MF_00206}. CC -!- FUNCTION: Catalyzes the transfer of endogenously produced octanoic CC acid from octanoyl-acyl-carrier-protein onto the lipoyl domains of CC lipoate-dependent enzymes. Lipoyl-ACP can also act as a substrate CC although octanoyl-ACP is likely to be the physiological substrate. CC {ECO:0000256|HAMAP-Rule:MF_00013, ECO:0000256|SAAS:SAAS00848413}.

One cluster is CC coordinated with 3 cysteines and an exchangeable S-adenosyl-L- CC methionine. {ECO:0000256|HAMAP-Rule:MF_00206}; CC -!- PATHWAY: Protein modification; protein lipoylation via endogenous CC pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier- CC protein]: step 2/2. {ECO:0000256|HAMAP-Rule:MF_00206}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00013, CC ECO:0000256|SAAS:SAAS00848401}. CC -!- MISCELLANEOUS: In the reaction, the free carboxyl group of CC octanoic acid is attached via an amide linkage to the epsilon- CC amino group of a specific lysine residue of lipoyl domains of CC lipoate-dependent enzymes. {ECO:0000256|HAMAP-Rule:MF_00013}.
