== 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. Keto acyl carrier protein 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>

== Disease == Deficiency of the KAR or mtFAS pathway leads to respiratory chain defects and mitochondrial dysfunction in eukaryotes.
