Production of human papillomavirus type 16 E7 protein in Lactococcus lactis.

The E7 protein of human papillomavirus type 16 was produced in Lactococcus lactis. Secretion allowed higher production yields than cytoplasmic production. In stationary phase, amounts of cytoplasmic E7 were reduced, while amounts of secreted E7 increased, suggesting a phase-dependent intracellular proteolysis. Fusion of E7 to the staphylococcal nuclease, a… CONTINUE READING
