Mitochondrial lipoyltransferase 1 (LIPT1) catalyses the transfer of a lipoyl group from lipoyl-K107-GCSH to lysine residue(s) of lipoate-dependent enzymes (Fujiwara et al. 1999; Cao et al., 2018). Defects in LIPT1 reduce lipoylation of pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase, causing a cofactor disorder of mitochondrial energy metabolism (Soreze et al. 2013, Tort et al. 2014; Ni et al., 2019).
