"Partly Folded" State, a New Equilibrium State of Protein Molecules: Four-state Guanidinium Chloride-induced Unfolding of .Beta.-lactamase at Low Temperature
Digital Object Identifier (DOI)
The Guanidinium chloride (GdmCl)-induced unfolding of β-lactamase has been investigated using a combination of size-exclusion chromatography (SEC-FPLC) and traditional optical methods. It has been shown that at low temperatures, this protein unfolds through two equilibrium intermediates. The first of these intermediates is the molten globule state, while the other (which we have called a "partly folded" state) is less compact than the molten globule but much more compact than the unfolded state. It also preserves a substantial part of the secondary structure of the native or molten globule state.
