CC -!- FUNCTION: Catalyzes the transfer of endogenously produced octanoic acid
CC from octanoyl-acyl-carrier-protein onto the lipoyl domain of GcvH, an
CC intermediate carrier during protein lipoylation. Is also able to
CC catalyze the reverse reaction. Octanoyl-CoA can also act as a substrate
CC although very poorly. Does not display lipoate protein ligase activity,
CC despite its sequence similarity to LplA. {ECO:0000269|PubMed:20882995,
CC ECO:0000269|PubMed:21338420, ECO:0000269|PubMed:21338421}.
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:0000269|PubMed:20882995};
CC -!- PATHWAY: Protein modification; protein lipoylation via endogenous
CC pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-
CC protein]. {ECO:0000269|PubMed:20882995}.
CC -!- SUBUNIT: Monomer. {ECO:0000305|PubMed:20882995}.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene are auxotrophic for
CC lipoic acid when grown in minimal medium but grow as well as the wild-
CC type strain in the presence of lipoic acid. The requirement for lipoic
CC acid can be bypassed by addition of both acetate and branched-chain
CC fatty acid (BCFA) precursors. The mutant cells are devoid of lipoylated
CC proteins. {ECO:0000269|PubMed:21338420}.
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 The reaction proceeds via an octanoyl-thioester enzyme intermediate.
CC -!- SIMILARITY: Belongs to the octanoyltransferase LipM family.
CC {ECO:0000305}.
