Homologous Superfamily

Acyl-CoA dehydrogenase/oxidase, N-terminal domain superfamily (IPR037069)

Short name: AcylCoA_DH/ox_N_sf

Overlapping entries


Acyl-CoA dehydrogenases (EC: are a family of flavoproteins that catalyse the alpha,beta-dehydrogenation of acyl-CoA thioesters to the corresponding trans 2,3-enoyl CoA-products with the concomitant reduction of enzyme-bound FAD. Different family members share a high sequence identity, catalytic mechanisms, and structural properties, but differ in the position of their catalytic bases and in their substrate binding specificity. Butyryl-CoA dehydrogenase [PMID: 11812788] prefers short chain substrates, medium chain- and long-chain acyl-CoA dehydrogenases prefer medium and long chain substrates, respectively, and Isovaleryl-CoA dehydrogenase [PMID: 9214289] prefers branched-chain substrates.

The monomeric enzyme is folded into three domains of approximately equal size, where the N-terminal domain is all-alpha, the middle domain is an open (5,8) barrel, and the C-terminal domain is a four-helical bundle. The constituent families differ in the numbers of C-terminal domains. This entry represents the N-terminal alpha-helical domain superfamily found in medium chain acyl-CoA dehydrogenases, as well as in the related peroxisomal acyl-CoA oxidase-II enzymes. Acyl-CoA oxidase (ACO; EC: catalyzes the first and rate-determining step of the peroxisomal beta-oxidation of fatty acids [PMID: 11872165].
