Characterization of KPC‐2 Backbone Dynamics Upon Avibactam Binding via NMR Spectroscopic Methods

Comparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation

Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...

Backbone dynamics of deoxy and carbonmonoxy hemoglobin by NMR/SRLS.

The slowly relaxing local structure (SRLS) approach, developed for NMR spin relaxation analysis in proteins, is applied herein to amide ¹⁵N relaxation in deoxy and carbonmonoxy hemoglobin. Experimental data including ¹⁵N T₁, T₂ and ¹⁵N-{¹H} NOE, acquired at 11.7 and 14.1 T, and 29 and 34 °C, are analyzed. The restricted local motion of the N-H bond is described in terms of the principal value (...

NMR spectroscopic characterization of the adenine-dependent hairpin ribozyme.

Time-resolved NMR spectroscopy was applied to study ribozyme-mediated RNA catalysis in a mutant of the hairpin ribozyme, the adenine-dependent hairpin ribozyme (ADHR; M. Meli, et al. J. Biol. Chem. 2003, 278, 9835-9842) with atomic resolution. The mutant ADHR was designed to investigate the role of cofactors in RNA catalytic mechanisms in order to understand cellular processes that could have b...
