Abstract
A process of producing a foreign protein is provided which comprises transforming E. coli with a plasmid carrying a fused DNA having a DNA fragment encoding a foreign protein located downstream of a transcription initiation signal and translation initiation signal both derived from an appropriate T4 phage gene, infecting the transformant with a T4 phase denB and/or alc mutant at a low multiplicity of infection, and then culturing the infected transformant. The desired foreign protein can be produced in an extremely high yield, as compared to the prior art technique.
