Gene Gene information from NCBI Gene database.
Entrez ID 11019
Gene name Lipoic acid synthetase
Gene symbol LIAS
Synonyms (NCBI Gene)
HGCLASHUSSY-01LASLIP1LSPDHLD
Chromosome 4
Chromosome location 4p14
Summary The protein encoded by this gene belongs to the biotin and lipoic acid synthetases family. Localized in the mitochondrion, this iron-sulfur enzyme catalyzes the final step in the de novo pathway for the biosynthesis of lipoic acid, a potent antioxidant. T

Protein name Lipoyl synthase, mitochondrial (EC 2.8.1.8) (Lipoate synthase) (LS) (Lip-syn) (Lipoic acid synthase)
Protein 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.
