ETFA
Appearance
Template:PBB Electron-transfer-flavoprotein, alpha polypeptide (glutaric aciduria II), also known as ETFA, is a protein which in humans is encoded by the ETFA gene.[1]
ETFA participates in catalyzing the initial step of the mitochondrial fatty acid beta oxidation. It shuttles electrons between primary flavoprotein dehydrogenases and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. Defects in electron-transfer-flavoprotein have been implicated in type II glutaricaciduria in which multiple acyl CoA dehydrogenase deficiencies result in large excretion of glutaric, lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids.[1]
