IUBMB Comments

A flavoprotein (FAD). The mammalian enzyme catalyses an oxidative reaction as a step in the mitochondrial β-oxidation of short-chain 2-methyl fatty acids and participates in isoleucine degradation. The enzyme from the parasitic helminth Ascaris suum catalyses a reductive reaction as part of a fermentation pathway, shuttling reducing power from the electron-transport chain to 2-methyl branched-chain enoyl CoA.

The expected taxonomic range for this enzyme is: Eukaryota, Bacteria

Synonyms
sbcad, sbcadd, short/branched chain acyl-coa dehydrogenase, 2-methylbutyryl-coa dehydrogenase, 2mbcd, 2-methyl branched-chain acyl-coa dehydrogenase, 2-methyl branched-chain enoyl-coa reductase, 2-methyl branched-chain enoyl coa reductase, 2-methyl branched chain acyl-coa dehydrogenase, more
