RC STRAIN=PRh5 {ECO:0000313|EMBL:EXU62426.1, RC ECO:0000313|Proteomes:UP000019949}; RA Zhu D., Yang H., Wang Y., Zhang Z., Yan R.; RT "Whole-genome shotgun assembly and analysis of the genome of Streptomyces RT sp. PRh5, a strain for production of geldanamycin, nigericin and RT nocardamine."; RL Submitted (JAN-2014) to the EMBL/GenBank/DDBJ databases. 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:0000256|ARBA:ARBA00024732, ECO:0000256|HAMAP-Rule:MF_00013, CC ECO:0000256|PIRNR:PIRNR016262}. 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:0000256|ARBA:ARBA00000953, ECO:0000256|HAMAP- CC Rule:MF_00013, ECO:0000256|PIRNR:PIRNR016262}; 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:0000256|ARBA:ARBA00004821, ECO:0000256|HAMAP- CC Rule:MF_00013, ECO:0000256|PIRNR:PIRNR016262}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|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:0000256|HAMAP-Rule:MF_00013}. CC -!- SIMILARITY: Belongs to the LipB family. {ECO:0000256|HAMAP- CC Rule:MF_00013, ECO:0000256|PIRNR:PIRNR016262}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:EXU62426.1}.
