The influence of N7 guanine modification on the strength of Watson-Crick base pairing and guanine N1 acidity: comparison of gas-phase and condensed-phase trends

Article Abstract:

Ab initio quantum-chemical calculations were carried out to investigate the correlation between Ni-Hi deprotonation energy and base pairing of modified guanines and dicationic platinated guanines. In the gas phase, the stability of the base pair increases with acidification of the N1(H1) position.

An improved picture of methyl dynamics in proteins from slowly relaxing local structure analysis of [super 2]H spin relaxation

Article Abstract:

An analysis of the [super 2]H spin relaxation slowly relaxing local structure (SRLS) is conducted to explain the methyl dynamics in different proteins. The results demonstrate that the rhombicity of the proteins decrease with an increase in the temperature.
