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.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.

(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
