    • DNA sequences, recombinant DNA molecules and hosts transformed with them which produce polypeptides displaying a biological or immunological activity of gamma interferon. The genes coding for these polypeptides and methods of making and using these DNA sequences, molecules, hosts, genes and polypeptides are disclosed. The DNA sequences of this invention are further characterized by expression control sequences which permit the production of gamma interferon in high yields. More particularly, these expression control sequences comprise the .lambda. P.sub.L promoter, and more preferably, a trp-derived expression control sequence containing the sequence ATCGATACT between the Shine-Dalgarno sequence and the translational start signal. In appropriate hosts, these DNA sequences and recombinant DNA molecules permit the production and identification of genes and polypeptides displaying a biological or immunological activity of gamma interferon and their use in antiviral, antitumor or anticancer, and immunomodulation agents and methods.
    • DNA序列,重组DNA分子和用它们转化的宿主,其产生显示γ干扰素的生物学或免疫学活性的多肽。 公开了编码这些多肽的基因以及制备和使用这些DNA序列,分子,宿主,基因和多肽的方法。 本发明的DNA序列的进一步特征在于允许以高产率生产γ干扰素的表达控制序列。 更具体地说,这些表达控制序列包括λPL启动子,更优选地,含有Shine-Dalgarno序列和翻译起始信号之间的序列ATCGATACT的trp衍生的表达控制序列。 在适当的宿主中,这些DNA序列和重组DNA分子允许产生和鉴定表现出γ干扰素的生物学或免疫学活性的基因和多肽及其在抗病毒,抗肿瘤或抗癌剂中的用途以及免疫调节剂和方法。
