Genomic Sci. 4:293-302(2011). CC -!- FUNCTION: Catalyzes the radical-mediated insertion of two sulfur atoms CC into the C-6 and C-8 positions of the octanoyl moiety bound to the CC lipoyl domains of lipoate-dependent enzymes, thereby converting the CC octanoylated domains into lipoylated derivatives. {ECO:0000255|HAMAP- CC Rule:MF_00206}.
