An investigation into structural changes due to deuteration
There has been a growth in the experimental determination of the protonation states of proteins. In this study the effect of deuteration on structure was examined by data mining, which yielded 52 small-molecule crystal structures as deuterated and hydrogenated pairs. Differences between these small-molecule structures have been calculated and the results thus far follow the initial assumption. With time, it will become possible to analyse for any differences, at a significant level of precision, of a large cohort of ultra-high-resolution protein structures in H and D forms.
