NMR-Chemical-Shift-Driven Protocol Reveals the Cofactor-Bound, Complete Structure of Dynamic Intermediates of the Catalytic Cycle of Oncogenic KRAS G12C Protein and the Significance of the Mg2+ Ion
In this work, catalytically significant states of the oncogenic G12C variant of KRAS, those of Mg^(2+)-free and Mg^(2+)-bound GDP-loaded forms, have been determined using CS-Rosetta software and NMR-data-driven molecular dynamics simulations. There are several Mg^(2+)-bound G12C KRAS/GDP structures deposited in the Protein Data Bank (PDB), so this system was used as a reference, while the structure of the Mg^(2+)-free but GDP-bound state of the RAS cycle has not been determined previously.

Abstract
K-Ras is a key driver of oncogenesis, accounting for approximately 80% of Ras-driven human cancers. The small GTPase cycles between an inactive, GDP-bound and an active, GTP-bound state, regulated by...

Complete determination of the Pin1 catalytic domain thermodynamic cycle by NMR lineshape analysis
Complete determination of the Pin1 catalytic domain thermodynamic cycle by NMR lineshape analysis
Abstract The phosphorylation-specific peptidyl-prolyl isomerase Pin1 catalyzes the isomerization of the peptide bond preceding a proline residue between cis and trans isomers. To best understand the mechanisms of Pin1 regulation, rigorous enzymatic assays of isomerization are required. However, most measures of isomerase activity require significant constraints on substrate sequence and only yield rate constants for the cis isomer,
kcatcis and apparent Michaelis constants,
