Acyl-CoA dehydrogenase; Both mitochondrial acyl-CoA dehydrogenases (ACAD) and peroxisomal acyl-CoA oxidases (AXO) catalyze the alpha,beta dehydrogenation of the corresponding trans-enoyl-CoA by FAD, which becomes reduced. The reduced form of ACAD is reoxidized in the oxidative half-reaction by electron-transferring flavoprotein (ETF), from which the electrons are transferred to the mitochondrial respiratory chain coupled with ATP synthesis. In contrast, AXO catalyzes a different oxidative half-reaction, in which the reduced FAD is reoxidized by molecular oxygen. The ACAD family includes the eukaryotic beta-oxidation enzymes, short (SCAD), medium (MCAD), long (LCAD) and very-long (VLCAD) chain acyl-CoA dehydrogenases. These enzymes all share high sequence similarity, but differ in their substrate specificities. The ACAD family also includes amino acid catabolism enzymes such as Isovaleryl-CoA dehydrogenase (IVD), short/branched chain acyl-CoA dehydrogenases(SBCAD), Isobutyryl-CoA dehydrogenase (IBDH), glutaryl-CoA deydrogenase (GCD) and Crotonobetainyl-CoA dehydrogenase. The mitochondrial ACAD's are generally homotetramers, except for VLCAD, which is a homodimer. Related enzymes include the SOS adaptive reponse proten aidB, Naphthocyclinone hydroxylase (NcnH), and and Dibenzothiophene (DBT) desulfurization enzyme C (DszC)

Peroxisomal acyl-CoA oxidase; Peroxisomal acyl-CoA oxidases (AXO) catalyze the first set in the peroxisomal fatty acid beta-oxidation, the alpha,beta dehydrogenation of the corresponding trans-enoyl-CoA by FAD, which becomes reduced. In a second oxidative half-reaction, the reduced FAD is reoxidized by molecular oxygen. AXO is generally a homodimer, but it has been reported to form a different type of oligomer in yeast. There are several subtypes of AXO's, based on substrate specificity. Palmitoyl-CoA oxidase acts on straight-chain fatty acids and prostanoids; whereas, the closely related Trihydroxycoprostanoly-CoA oxidase has the greatest activity for 2-methyl branched side chains of bile precursors. Pristanoyl-CoA oxidase, acts on 2-methyl branched fatty acids. AXO has an additional domain, C-terminal to the region with similarity to acyl-CoA dehydrogenases, which is included in this alignment.

Proteins involved in DNA damage response, similar to the AidB gene product; AidB is one of several genes involved in the SOS adaptive response to DNA alkylation damage, whose expression is activated by the Ada protein. Its function has not been entirely elucidated; however, it is similar in sequence and function to acyl-CoA dehydrogenases. It has been proposed that aidB directly destroys DNA alkylating agents such as nitrosoguanidines (nitrosated amides) or their reaction intermediates.
