title: Purification and some properties of alcohol oxidase from alkane-grown Candida tropicalis.
abstract: Alcohol oxidase was purified to homogeneity from membrane fractions obtained from alkane-grown Candida tropicalis. The enzyme appears to be a dimer of equal-sized subunits of Mr 70000. The purified enzyme is photosensitive and contains flavin-type material which is released by a combination of boiling and proteolytic digestion. The identity of the flavin material is not yet known, but it is not FMN, FAD or riboflavin. The enzyme is most active with dodecan-I-ol, but other long-chain alcohols are also attacked. The enzyme shows a weak, but significant activity towards long-chain aldehydes. Detailed kinetic studies with decan-1-ol as substrate suggest a group-transfer (Ping-Pong)-type mechanism of catalysis.
