Abstract

A gene cluster has been isolated from an Acinetobacter sp. that encodes the enzymes expected to convert cyclohexanol to adipic acid. The entire gene cluster has been cloned and all open reading frames have been sequenced. Cosmid clones have been identified containing the gene cluster. Demonstration of conversion of cyclohexanol to adipic acid has been made with the recombinant E. coli host strain containing the cosmids.
