Abstract
Disclosed is a new enzyme, aldehyde oxidase, which catalyzes the oxidation of an aldehyde to a corresponding acid but does not have any catalytic action upon other substrates. Also disclosed is a fermentative process from producing the enzyme.
Claims6
Aldehyde oxidase characterized by:
- a molecular weight of about 110,000, an optimum pH of about 6.5 and an optimum temperature of about 50.degree. C., wherein the oxidase catalyzes the oxidation reaction of an aldehyde to a corresponding acid and does not exhibit substrate activity to the group of compounds including N'-methylnicotinamide, quinoline, purine, hepoxanthine and quinine.
A biologically pure culture of the microorganism Pseudomonas sp. No. 6233, FERM P-6467, which produces recoverable quantities of aldehyde oxidase when cultured.
