Kinetic studies of the refolding of yeast phosphoglycerate kinase: comparison with the isolated engineered domains.

Unfolding and refolding kinetics of yeast phosphoglycerate kinase were studied by following the time-dependent changes of two signals: the ellipticity at 218 nm and 222 nm, and the fluorescence emission at 330 nm (following excitation at 295 nm). The protein is composed of two similar-sized structural domains. Each domain has been produced by recombinant DNA techniques.
