Plasmid-derived expression of the human CyPA in E. coli would make it possible to obtain ample protein quantities and to avoid difficult task of obtaining human tissues for protein purification. The cDNA encoding human CyPA from MT4 lymph cell line has been cloned and an expression vector (pET11/CyPA) has been constructed under control of the T7 promoter for efficient expression in E. coli. The recombinant CyPA is produced at 41% of total soluble cell protein, and showed the peptidyl-prodyl cis-trans isomerase activity.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
