General Information

General Information Comment Organism
malfunction enzyme deficiency can cause multiple acyl-CoA dehydrogenase deficiency, MADD. The inability to oxidize fatty acids prevents the synthesis of ketone bodies, an essential alternate energy source for the heart. Affected individuals frequently die in early infancy with a severe, frequently fatal, metabolic acidosis that is often accompanied by a stress-induced hypertrophic cardiomyopathy and lipid accumulation in the heart, and secondary carnitine deficiency Sus scrofa
additional information the enzyme is a component of the mitochondrial respiratory chain that together with electron transfer flavoprotein (ETF) forms a short pathway that transfers electrons from 11 different mitochondrial flavoprotein dehydrogenases to the ubiquinone pool, ETF:QO enzyme structure and its quinone binding site, domain organisation, overview Sus scrofa
