title: Expression of cloned beta-endorphin gene sequences by Escherichia coli.
abstract: DNA coding for the opiate peptide beta-endorphin has been cloned into bacterial plasmids in such a way as to direct the synthesis of a hybrid beta-galactosidase/beta-endorphin protein. This hybrid protein can readily be cleaved in vitro to release biologically active beta-endorphin.
