Protein: Lipoyl synthase (EC 2.8.1.8) (Lip-syn) (LS) (Lipoate synthase) (Lipoic acid synthase) (Sulfur insertion protein LipA) (O32129)
Organism: Bacillus subtilis (strain 168)
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.
Subcellular location: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00206}.
InterPro domains:
- IPR007197: Radical SAM (domain) [3-290]
- IPR003698: Lipoyl synthase (family) [1-298]
- IPR031691: Lipoyl synthase, N-terminal (domain) [3-45]
- IPR006638: Elp3/MiaA/NifB-like, radical SAM core domain (domain) [57-265]
- IPR013785: Aldolase-type TIM barrel (homologous_superfamily) [6-266]
