It is necessary to establish strategy for RNase H detection. ... resulting in the … WebWe conclude that the guanidine-unfolded state of RNase A is an equilibrium mixture of fast- and slow-refolding species, as was found previously for the heat-unfolded state at low pH. The fraction of the fast-refolding species in guanidine or urea-unfolded RNase A is the …
WebSecondary structural characteristic of various denatured states of RNase-A at pH 7.0. The GdmCl- and urea- induced denatured states were generated using 6.5 M GdmCl and 8.5 M … WebWe conclude that the guanidine-unfolded state of RNase A is an equilibrium mixture of fast- and slow-refolding species, as was found previously for the heat-unfolded state at low pH. The fraction of the fast-refolding species in guanidine or urea-unfolded RNase A is the same as that in the heat-unfolded protein at pH 2.
WebNov 30, 2024 · Many in vitro studies, in which proteins have been unfolded by the action of a variety of physical or chemical agents, have led to the definition of a folded versus an unfolded state and to the question of what is the nature of the unfolded state. The unstructured nature of this state could suggest that “the” unfolded state is a unique entity … WebOct 14, 2014 · These conclusions have been reached from the systematic measurements of enzymatic kinetic parameters (Km and kcat), thermodynamic stability (Tm and ΔHm) and secondary and tertiary structures of the folded native proteins obtained from refolding of various denatured states (due to heat-, urea- and GdmCl-induced denaturation) of RNase …
