Role of the molybdoflavoenzyme aldehyde oxidase homolog 2 in the biosynthesis of retinoic acid: generation and characterization of a knockout mouse.
Terao M., Kurosaki M., Barzago M.M., Fratelli M., Bagnati R., Bastone A., Giudice C., Scanziani E., Mancuso A., Tiveron C., Garattini E.
The mouse aldehyde oxidase AOH2 (aldehyde oxidase homolog 2) is a molybdoflavoenzyme. Harderian glands are the richest source of AOH2, although the protein is detectable also in sebaceous glands, epidermis, and other keratinized epithelia.

The mouse aldehyde oxidase AOH2 (aldehyde oxidase homolog 2) is a molybdoflavoenzyme. Harderian glands are the richest source of AOH2, although the protein is detectable also in sebaceous glands, epidermis, and other keratinized epithelia. The levels of AOH2 in the Harderian gland and skin are controlled by genetic background, being maximal in CD1 and C57BL/6 and minimal in DBA/2, CBA, and 129/Sv strains. Testosterone is a negative regulator of AOH2 in Harderian glands. Purified AOH2 oxidizes retinaldehyde into retinoic acid, while it is devoid of pyridoxal-oxidizing activity. Aoh2(-/-) mice, the first aldehyde oxidase knockout animals ever generated, are viable and fertile. The data obtained for this knockout model indicate a significant role of AOH2 in the local synthesis and biodisposition of endogenous retinoids in the Harderian gland and skin. The Harderian gland's transcriptome of knockout mice demonstrates overall downregulation of direct retinoid-dependent genes as well as perturbations in pathways controlling lipid homeostasis and cellular secretion, particularly in sexually immature animals. The skin of knockout mice is characterized by thickening of the epidermis in basal conditions and after UV light exposure. This has correlates in the corresponding transcriptome, which shows enrichment and overall upregulation of genes involved in hypertrophic responses. << Less

Retinal oxidase is identical to aldehyde oxidase.
Tomita S., Tsujita M., Ichikawa Y.
Retinal oxidase (EC 1.2.3.11) and aldehyde oxidase (EC 1.2.3.1) were compared with respect to their enzymatic and physiochemical properties. It was found that the molecular weights, subunits, optical spectra, chemical and immunological properties, cellular localization and substrate specificities ... >> More
Retinal oxidase (EC 1.2.3.11) and aldehyde oxidase (EC 1.2.3.1) were compared with respect to their enzymatic and physiochemical properties. It was found that the molecular weights, subunits, optical spectra, chemical and immunological properties, cellular localization and substrate specificities of the two oxidases are identical on almost all points. The physiological function of aldehyde oxidase appears to be the synthesis of retinoic acid from retinal. << Less

Molecular cloning of retinal oxidase/aldehyde oxidase cDNAs from rabbit and mouse livers and functional expression of recombinant mouse retinal oxidase cDNA in Escherichia coli.
Huang D.-Y., Furukawa A., Ichikawa Y.
Retinal oxidase (EC 1.2.3.11) is a molybdenum-containing flavoenzyme with high enzymatic activity as to retinoic acid synthesis. In this study, we provide direct evidence that retinal oxidase is identical to aldehyde oxidase (EC 1.2.3.1) by cDNA cloning. Retinal oxidase and aldehyde oxidase, purif ... >> More
Retinal oxidase (EC 1.2.3.11) is a molybdenum-containing flavoenzyme with high enzymatic activity as to retinoic acid synthesis. In this study, we provide direct evidence that retinal oxidase is identical to aldehyde oxidase (EC 1.2.3.1) by cDNA cloning. Retinal oxidase and aldehyde oxidase, purified from rabbit liver cytosol using the original methods, showed completely identical HPLC patterns and amino acid sequences for three corresponding polypeptides (103 amino residues). The primary structural information obtained from the cleaved polypeptides permitted molecular cloning of the full-length cDNA of rabbit liver retinal oxidase (aldehyde oxidase). We also cloned and sequenced the full-length cDNA of mouse retinal oxidase. The cDNAs of rabbit and mouse retinal oxidase have a common sequence approximately 4.6 kb long, comprising 4-kb coding regions. The open reading frames of the cDNAs predict single polypeptides of 1334 and 1333 amino acids; the calculated minimum molecular mass of each is approximately 147,000. Northern blot analysis showed that the rabbit retinal oxidase mRNA was widely expressed in tissues. Finally, we successfully constructed a prokaryotic expression system for mouse retinal oxidase. The purified recombinant retinal oxidase from Escherichia coli showed a typical spectrum of aldehyde oxidases and a lower Km (3.8 microM) for retinal and a higher Vmax (807 nmol/min/mg protein) for retinoic acid synthesis than those of rabbit retinal oxidase (8 microM and 496 nmol/min/mg protein). This represents the first eukaryotic molybdenum-containing flavoprotein to be expressed in an active form in a prokaryotic system. << Less
