柔嫩艾美耳球虫G6-PI基因的克隆、序列分析与原核表达
CLONING, SEQUENCE ANALYSIS AND PROKARYOTIC EXPRESSION OF GLUCOSE-6-PHOSPHATE ISOMERASE OF EIMERIATENELLA
摘要
Abstract
In order to analyze biochemical properties of Eimeria tenella glucose-6- phosphate isomerase EtG6-PI, the full-length of open reading frame Etg6-PI was amplified in RT-PCR from total RNA from the second-generation schizonts of E.tenella. The amplified fragments were Results showed that the open reading frame was 1650 bp, sequenced. The Etg6-PI gene was cloned into the expression vectors pColdI and pCold43a and expressed in E. coli Rosetta (DE3). encoded a protein of 550 amino acids. The recombinant vectors pColdI-EtG6-PI or pCold43a-EtG6-PI was transformed into E. coli Rosetta (DE3) cells and the expression was induced with IPTG Soluble protein obtained from pCold43a-EtG6-PI purifide by the affinity chromatography assay can be used for biochemical analysis of this enzyme. The prokaryotic expression of E.tenella G6-PI set important basis for function study on glucose-6-phosphate isomerase.关键词
