Hydrogen exchange results for cytochrome c have been interpreted in terms of transient hydrogen bond-breaking reactions that include large unfolding reactions and small fluctuational distortions. The differential sensitivity of these opening reactions to denaturant, temperature, and protein stability makes it possible to distinguish the different opening(More)
It has been suggested that three partially unfolded forms detected in a native state hydrogen exchange study of oxidized cytochrome c may represent sequential intermediates in an unfolding-refolding pathway. To better define the structure of each intermediate a 'stability labeling' method was used in which the stability of a given segment against unfolding(More)
The nickel(II) catalyst has manifested higher catalytic activity compared to that of other late transition metal catalysts for norbornene polymerization. Therefore, several structurally similar trans-nickel(II) compounds of N,O-chelate bidentate ligands were synthesized and characterized. Both the electronic effect and the steric hindrance influence(More)
