CC   -!- FUNCTION: Catalyzes the transfer of endogenously produced octanoic acid
CC       from octanoyl-acyl-carrier-protein onto the lipoyl domains of lipoate-
CC       dependent enzymes. Lipoyl-ACP can also act as a substrate although
CC       octanoyl-ACP is likely to be the physiological substrate.
CC       {ECO:0000255|HAMAP-Rule:MF_00013}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-lysyl-[protein] + octanoyl-[ACP] = H(+) + holo-[ACP] + N(6)-
CC         octanoyl-L-lysyl-[protein]; Xref=Rhea:RHEA:17665, Rhea:RHEA-
CC         COMP:9636, Rhea:RHEA-COMP:9685, Rhea:RHEA-COMP:9752, Rhea:RHEA-
CC         COMP:9928, ChEBI:CHEBI:15378, ChEBI:CHEBI:29969, ChEBI:CHEBI:64479,
CC         ChEBI:CHEBI:78463, ChEBI:CHEBI:78809; EC=2.3.1.181;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00013};
CC   -!- PATHWAY: Protein modification; protein lipoylation via endogenous
CC       pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-
CC       protein]: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00013}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00013}.
CC   -!- MISCELLANEOUS: In the reaction, the free carboxyl group of octanoic
CC       acid is attached via an amide linkage to the epsilon-amino group of a
CC       specific lysine residue of lipoyl domains of lipoate-dependent enzymes.
CC       {ECO:0000255|HAMAP-Rule:MF_00013}.
CC   -!- SIMILARITY: Belongs to the LipB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00013}.
