This study investigates deuteron incorporation in hen egg lysozyme, equine lysozyme, the catalytic subunit of PKA E230Q, and the α-actinin CH2 domain, employing DXCOREX calculations. The results are compared with NMR-determined values, highlighting the correlation between calculated and experimentally determined incorporation levels. Figures illustrate the regression analysis of deuteron incorporation per peptide across several proteins, revealing varying levels of proteomic behavior in different pH conditions. This work contributes to our understanding of protein dynamics and interactions.
