Abstract
Chemically synthesized alpha-neo-endorphin gene was fused to the Escherichia coli beta-galactosidase gene on the plasmid pKO13. The resulting recombinant DNA was used to transform E. coli cells. Radioimmunoassay for alpha-neo-endorphin in CNBr-treated bacterial cells showed that alpha-neo-endorphin was synthesized at approximately 5 x 10(5) molecules per single E. coli cell. One of the transformants, WA802/p alpha NE2, was used for alpha-neo-endorphin purification. From 10.9 g of wet cells, we isolated 4 mg of chemically pure and biologically active alpha-neo-endorphin.Entities:
