CC   -!- FUNCTION: Catalyzes the amidotransfer (transamidation) of the octanoyl
CC       moiety from octanoyl-GcvH to the lipoyl domain of the E2 subunit of
CC       lipoate-dependent enzymes. {ECO:0000255|HAMAP-Rule:MF_02119}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-lysyl-[lipoyl-carrier protein] + N(6)-octanoyl-L-lysyl-
CC         [glycine-cleavage complex H protein] = L-lysyl-[glycine-cleavage
CC         complex H protein] + N(6)-octanoyl-L-lysyl-[lipoyl-carrier protein];
CC         Xref=Rhea:RHEA:20213, Rhea:RHEA-COMP:10500, Rhea:RHEA-COMP:10501,
CC         Rhea:RHEA-COMP:10503, Rhea:RHEA-COMP:10504, ChEBI:CHEBI:29969,
CC         ChEBI:CHEBI:78809; EC=2.3.1.204; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_02119};
CC   -!- PATHWAY: Protein modification; protein lipoylation via endogenous
CC       pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-
CC       protein]. {ECO:0000255|HAMAP-Rule:MF_02119}.
CC   -!- MISCELLANEOUS: The reaction proceeds via a thioester-linked acyl-enzyme
CC       intermediate. {ECO:0000255|HAMAP-Rule:MF_02119}.
CC   -!- SIMILARITY: Belongs to the octanoyltransferase LipL family.
CC       {ECO:0000255|HAMAP-Rule:MF_02119}.
