A5CQ99 · LIPA_CLAM3

Function

function

Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives.

Catalytic activity

Cofactor

[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.

Pathway

Protein modification; protein lipoylation via endogenous pathway; protein N6-(lipoyl)lysine from octanoyl-[acyl-carrier-protein]: step 2/2.
