To clone the Eg95 and EgA31 antigen genes into the prokaryotic expression plasmid pET30a-EgA31-Eg95, we expressed the recombinant protein EgA31-Eg95 and confirmed with western blot analysis. The total RNA was extracted from the protoscoleces of Echinococcus granu-losus (E. granulosus) adult worms. The complementary DNA (cDNA) encoding the EgA31 antigen was(More)
The E. coli propionyl-CoA synthetase (PCS) was cloned, expressed, purified, and analyzed. Kinetic analyses suggested that the enzyme preferred propionate as substrate but would also use acetate. The purified, stored protein had relatively low activity but was activated up to about 10-fold by incubation with dithiothreitol (DTT). The enzyme activation by DTT(More)
