Cloning and sequencing of partial segment of cholesterol oxidase encoding gene from Streptomyces luridus

Abstract

Cloning, sequencing and analysis of partial segment of cholesterol oxidase (cho) encoding gene from Streptomyces luridus using PCR technique is described. The primers used for PCR were designed on the basis of inter-species homology, and the pTZ57R/T vector was used for molecular cloning. The sequencing results lead to identification of the oxidoreductase domain of cho enzyme with 818 nucleotide length encoding 272 amino acids, which was submitted in NCBI with DQ480365 accession number. The submitted sequence includes complete FAD-linked reductase C terminal domain with 170 amino acids size and N-terminal of GMC-oxidoreductase domain of cho enzyme.
