Abstract | Chicken egg ovalbumin is a non-inhibitory member of the serpin (serine protease inhibitors) family whose members share a common tertiary fold. In the present study, we succeeded in high-level production of a disulfide-free form of refolded recombinant ovalbumin. Conformational characterization of the recombinant ovalbumim revealed that it is well-folded, following two-state unfolding transition with the midpoint of transition at 4.7 M at 25°C. This value is very close to that of the reduced form of authentic ovalbumin. The recombinant ovalbumin can serve as a model molecule of non-inhibitory serpins in comparative studies with inhibitory members of the serpin family. |
