WebOct 9, 2024 · In crystallography, uncertainty in the positions of atoms increases with disorder in the protein crystal. Disorder may have two components, static and dynamic. Resolution represents the average uncertainty for all atoms. In contrast, the temperature value (also called temperature factor or B factor) quantitates the uncertainty for each atom. http://www.uoxray.uoregon.edu/tnt/guide/node41.html

In addition to nearby static disorder, the chloride anion is also disordered in 3. In this work, each sample is investigated by 1H, 1H 13C CPMAS,[17] and 35Cl solid-state NMR, and is supported by gauge-included projector augmented wave
WebJan 10, 2024 · Abstract Until recently, the occurrence of conformational entropy in protein crystal contacts was considered to be a very unlikely event. A study based on the most accurately refined protein structures demonstrated that side-chain conformational entropy and static disorder might be common in protein crystal lattices.
