Cloning and expression of a bpr gene encoding Bacillopeptidase F from Bacillus amyloliquefaciens CH86-1

J Microbiol Biotechnol. 2011 May;21(5):515-8. doi: 10.4014/jmb.1010.10061.

Abstract

A gene encoding bacillopeptidase F, bpr86-1, was cloned from B. amyloliquefaciens CH86-1 isolated from cheonggukjang. This gene could encode a preproenzyme of 1,431 amino acids. When bpr86-1 was introduced into B. subtilis WB600 via pHY300PLK, an E. coli-Bacillus shuttle vector, the transformant showed fibrinolytic activity. During growth on LB, the fibrinolytic activity of cells increased sharply when they entered the stationary phase. The highest activity (761.4 mU/mg protein) was observed at 96 h of cultivation.
