GO:0016937 butyryl dehydrogenase Catalysis of the reaction: a short-chain 2,3-saturated fatty acyl-CoA + H+ + oxidized [electron-transfer flavoprotein] = a short-chain (2E)-enoyl-CoA + reduced [electron-transfer flavoprotein]. A short-chain fatty acid has an aliphatic tail containing fewer than 6 carbons. unsaturated acyl-CoA reductase KEGG_REACTION:R01178 RHEA:24004 UM-BBD_reactionID:r0013 short-chain acyl CoA dehydrogenase
