UniProt functional annotation for Q5SLQ3

UniProt code: Q5SLQ3.

Organism: Thermus thermophilus (strain ATCC 27634 / DSM 579 / HB8).
Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Thermales; Thermaceae; Thermus.
 
Function: Catalyzes the transfer of endogenously produced octanoic acid from octanoyl-acyl-carrier-protein onto the lipoyl domains of lipoate- dependent enzymes. Lipoyl-ACP can also act as a substrate although octanoyl-ACP is likely to be the physiological substrate. {ECO:0000255|HAMAP-Rule:MF_00013}.
 
Catalytic activity: Reaction=L-lysyl-[protein] + octanoyl-[ACP] = H(+) + holo-[ACP] + N(6)- octanoyl-L-lysyl-[protein]; Xref=Rhea:RHEA:17665, Rhea:RHEA- COMP:9636, Rhea:RHEA-COMP:9685, Rhea:RHEA-COMP:9752, Rhea:RHEA- COMP:9928, ChEBI:CHEBI:15378, ChEBI:CHEBI:29969, ChEBI:CHEBI:64479, ChEBI:CHEBI:78463, ChEBI:CHEBI:78809; EC=2.3.1.181; Evidence={ECO:0000255|HAMAP-Rule:MF_00013};
Pathway: Protein modification; protein lipoylation via endogenous pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier- protein]: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00013}.
Subcellular location: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00013}.
Miscellaneous: In the reaction, the free carboxyl group of octanoic acid is attached via an amide linkage to the epsilon-amino group of a specific lysine residue of lipoyl domains of lipoate-dependent enzymes. {ECO:0000255|HAMAP-Rule:MF_00013}.
Similarity: Belongs to the LipB family. {ECO:0000255|HAMAP- Rule:MF_00013}.
