Function

LPLAN_THEAC Part of a lipoate-protein ligase complex that catalyzes both the ATP-dependent activation of exogenously supplied lipoate to lipoyl-AMP and the transfer of the activated lipoyl onto the lipoyl domains of lipoate-dependent enzymes. Can also use octanoate as substrate.^[1] ^[2] ^[3]
