VP1, the major coat protein of polyomavirus, assembles intracellularly to virus-like particles if expressed in eukaryotes. Here, the nonconventional yeastKluyveromyces lactiswas used for production of virus-like particles of murine polyomavirus. The heterologous gene of VP1 was integrated in theLAC4locus of theGAL/LACgenes. Consequently the expression of VP1 is regulated by the interplay of the activator KlGal4p and inhibitor KlGal80p. This cloning strategy couples the production of VP1 to that of the enzyme β-galactosidase, allowing a fast alternative for monitoring the course of recombinant protein production by measuring the β-galactosidase activity. AKlgal80knockout strain was generated for a constitutive expression of VP1 and a continuous VLP production. High-cell-density fermentation showed that (1)Kluyveromyces lactisis generally suitable for VLP production and (2) theKlgal80knockout strain produces higher amounts of recombinant VP1.Furthermore, VLPs could be purified chromatographically to 87% (w/w) of total protein, and showed a homogeneous species of 45-nm particles and a high resistance against proteolysis compared to conventional in vitro assembled VLPs. This demonstrates the superior stability of virus-like particles produced in yeast. Supplemental materials are available for this article.
