  • 摘要:We applied the method of Guarente et al. [Guarente, L., Lauer, G., Roberts, T.M. & Ptashne, M. (1980) Cell 20, 543-553] to construct plasmids that direct expression in Escherichia coli of the human fibroblast interferon (F-IF) gene. Two plasmids were recovered. One directs efficient synthesis of a protein whose primary sequence is that of pre-F-IF and the other, that of mature F-IF. Extracts of bacteria synthesizing mature F-IF display antiviral activity characteristic of human F-IF. This activity is lower than that expected from the differential rate of synthesis of the protein. We have detected no such activity in extracts of bacteria synthesizing pre-F-IF.
