ABSTRACT:
Methods and vectors for expressing interferon-alpha (IFN-.alpha.) proteins in E. coli are provided. Use of a vector comprising an IFN-.alpha. sequence fused to an E. coli heat-stable enterotoxin signal sequence (STII) under the control of the E. coli phosphatase (phoA) promoter affords high levels of correctly-folded and -processed, biologically active IFN-.alpha. polypeptides.
