Backbone dynamics of Escherichia coli ribonuclease HI: correlations with structure and function in an active enzyme.
Ribonuclease H is an endonuclease that hydrolyzes the RNA moiety of RNA-DNA duplex molecules. Escherichia coli ribonuclease H is involved in DNA replication, and retroviral ribonuclease H is… Expand

Previous studies have suggested that the Ca2+-saturated E140Q mutant of the C-terminal domain of calmodulin exhibits equilibrium exchange between "open" and "closed" conformations similar to those of… Expand
Dynamics of ribonuclease H: temperature dependence of motions on multiple time scales.
The temperature dependence of the backbone motions in Escherichia coli ribonuclease HI was studied on multiple time scales by 15N nuclear magnetic spin relaxation. Laboratory frame relaxation data at… Expand
