Protein

Lipoyl synthase, mitochondrial

Gene

DEHA2G18854g

Organism
Debaryomyces hansenii (strain ATCC 36239 / CBS 767 / JCM 1990 / NBRC 0083 / IGC 2968) (Yeast) (Torulaspora hansenii)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Protein N6-(octanoyl)lysine + an [Fe-S] cluster scaffold protein carrying a [4Fe-4S]2+ cluster + 2 S-adenosyl-L-methionine + 2 oxidized [2Fe-2S] ferredoxin + 6 H+ = protein N6-(dihydrolipoyl)lysine + an [Fe-S] cluster scaffold protein + 2 sulfide + 4 Fe3+ + 2 L-methionine + 2 5'-deoxyadenosine + 2 reduced [2Fe-2S] ferredoxin.UniRule annotation

Cofactori

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

Pathwayi: protein lipoylation via endogenous pathway

This protein is involved in step 2 of the subpathway that synthesizes protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-protein].UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Octanoyltransferase (DEHA2G15862g)
  2. Lipoyl synthase, mitochondrial (DEHA2G18854g)
This subpathway is part of the pathway protein lipoylation via endogenous pathway, which is itself part of Protein modification.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-protein], the pathway protein lipoylation via endogenous pathway and in Protein modification.
