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 RT Streptomyces sp. PRh5, a strain for production of geldanamycin, RT nigericin and nocardamine."; RL Submitted (JAN-2014) to the EMBL/GenBank/DDBJ databases. 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|PIRNR:PIRNR016262, CC ECO:0000256|SAAS:SAAS00498847}. CC -!- CATALYTIC ACTIVITY: Octanoyl-[acyl-carrier-protein] + protein = CC protein N(6)-(octanoyl)lysine + [acyl-carrier-protein]. CC {ECO:0000256|HAMAP-Rule:MF_00013, ECO:0000256|PIRNR:PIRNR016262, CC ECO:0000256|SAAS:SAAS00498837}. CC -!- PATHWAY: Protein modification; protein lipoylation via endogenous CC pathway. {ECO:0000256|SAAS:SAAS00543046}. CC -!- PATHWAY: Protein modification; protein lipoylation via endogenous CC pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier- CC protein]. {ECO:0000256|SAAS:SAAS00572779}. 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|HAMAP-Rule:MF_00013, CC ECO:0000256|PIRNR:PIRNR016262, ECO:0000256|SAAS:SAAS00498839}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00013, CC ECO:0000256|SAAS:SAAS00498845}. 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}. CC -!- SIMILARITY: Belongs to the LipB family. {ECO:0000256|HAMAP- CC Rule:MF_00013, ECO:0000256|PIRNR:PIRNR016262, CC ECO:0000256|SAAS:SAAS00543055}. CC -!- SIMILARITY: Contains 1 BPL/LPL catalytic domain. CC {ECO:0000256|HAMAP-Rule:MF_00013}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:EXU62426.1}.
