Cloning and characterization of three fatty alcohol oxidase genes from Candida tropicalis strain ATCC 20336.

ABSTRACT: Candida tropicalis (ATCC 20336) converts fatty acids to long-chain dicarboxylic acids via a pathway that includes among other reactions the oxidation of omega-hydroxy fatty acids to omega-aldehydes by a fatty alcohol oxidase (FAO). Three FAO genes (one gene designated FAO1 and two putative allelic genes designated FAO2a and FAO2b), have been cloned and sequenced from this strain. A comparison of the DNA sequence homology and derived amino acid sequence homology between these three genes and previously published Candida FAO genes indicates that FAO1 and FAO2 are distinct genes. Both genes were individually cloned and expressed in Escherichia coli. The substrate specificity and K(m) values for the recombinant FAO1 and FAO2 were significantly different. Particularly striking is the fact that
