Anwendung

Alcohol oxidase is used to catalyze the oxidation of short-chain, primary, aliphatic alcohols to their respective aldehydes . It may be used to study methanol metabolism is yeasts, such as Candida, Pichia, and Hansenula. It is useful to study protein translocation into peroxisomes. Product A6941 is from Candida boidinii and is provided as a lyophilized powder.

Biochem./physiol. Wirkung

Alcohol oxidase has the highest affinity for methanol. The affinity decreases with increasing chain length of the alkyl (R) group. Alcohol oxidase is primarily localized in the peroxisome but is also found in the cytoplasm. Alcohol oxidase is a 600 kDa homooctomeric flavoprotein with eight equal 74 kDa subunits; each containing a flavin adenine dinucleotide (FAD) molecule. The enzyme shows little activity toward secondary, tertiary, or aromatic alcohols; or aliphatic alcohols with a chain length of more than 5 carbons. The pH range for activity of this product is 6.5-8.5, with the optimum pH being 7.5.

We identified a gene, designated TRM2, responsible for methanol-inducible gene expression in the methylotrophic yeast Candida boidinii. The encoded protein Trm2p contains two C(2)H(2)-type zinc finger motifs near the N terminus and shows high similarity to Saccharomyces cerevisiae Adr1p and
