The IPTG-inducible expression vector containing the BYDV GAV coat protein gene was constructed and transferred into E. coli BL21(DE3). High-level expression of the specific protein was achieved by IPTG induction. The results of SDS-PAGE and Western blotting show that the expression product which accumulates 19.5% of the total cellular proteins estimated by scanning is 24 kD BYDV GAV coat protein plus eleven amino acids of pET-5a.

D002213 Capsid The outer protein protective shell of a virus, which protects the viral nucleic acid. Capsids are composed of repeating units (capsomers or capsomeres) of CAPSID PROTEINS which when assembled together form either an icosahedral or helical shape. Procapsid,Prohead,Capsids,Procapsids,Proheads
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
