Abstract :
The nucleotide sequence of a 1.5-kb fragment of Pseudomonas pyrrocinia DNA containing the chloroperoxidase(CPO)-encoding gene (cpo) and its flanking regions was determined. The cpo codes for a protein of 278 amino acids (aa). The mature enzyme contains no N-terminal methionine, so that the CPO monomer consists of 277 aa with a calculated M(r) of 30,304. Expression studies showed that the cpo from P. pyrrocinia is functionally expressed in Escherichia coli and Streptomyces lividans. Based on the overproduction of the CPO in E. coli, a novel and simple purification procedure was developed allowing the isolation of about 800-fold more CPO per gram of cells than was originally isolated from P. pyrrocinia. Comparison with the aa sequence of the bromoperoxidase BPO-A2 from S. aureofaciens ATCC10762 revealed an identity of 38%. |
