    摘要: DNA comprising the naturally occurring nucleotide sequence coding for amino acids 44-90 of .beta.-lipotropin and including the entire coding region for .beta.-endorphin with the exception of the C-terminal glutamine was modified, transferred to an expression transfer vector, and expressed as a fusion protein. The fusion protein was further modified in vitro to yield mature .beta.-endorphin. .beta.-endorphin was purified from a bacterial lysate. The structure and biological activity of the resulting product was proven by immunological assay, and by two independent assays designed to demonstrate biological activity.
