Cloning and Optimization of Prokaryotic Expression of Quinolone Resistance Gene in Vibrio harveyi
摘要
Abstract
The sequence of quinolone resistance gene ofVibrio harveyi was cloned based on theqnr of Vibrio harveyi published on GenBank and then inserted into the pET-32a vector to construct prokaryotic expression plasmid pET32-qnr.Then the expression conditions of temperature, induction time,and IPTG concentration of the pET32-qnr were optimized.The results showed that the completeopen reading frame (ORF) length ofqnrgene was 651bp,encoding a protein of 216 amino acids. The optimization conditions of inducible expression for Qnr protein wereinducingin 0.05 mmol/L IPTG for 6 hoursat 28℃.关键词
