Function The mitochondrial fatty acid synthesis (mtFAS) pathway generates precursors for mitochondrally generated alpha-lipoic acids. Defeciency of mtFAS leads to respiratory chain degects and mitochondrial dysfunction. The mtFAS has four enzymatic steps, catalyzed by four different enzymes. Ketoacyl acyl-carrier-protein (ACP) reductase (KAR) catalyzes the second step of mtFAS pathway, where 3-ketoacyl-ACP is reduced to 3R-hydroxyacyl-ACP utilizing NADPH as cofactor. KAR is a heterotetrameric complex made from two different polypeptides: 17β-hydroxysteroid dehydrogenase type 8 (HSD17B8 or KE6, α-subunit) and carbonyl reductase type 4 (CBR4 or SDR45C1, β-subunit)9. <ref>PMID:25203508</ref> | |||
