Advanced Science, EarlyView.The crystal structures of UMG‐SP2, a metagenome‐derived urethanase that degrades polyurethane, have been solved at high resolution in both ligand‐free and ligand‐bound forms with an amidase inhibitor or a small carbamate. Structure‐guided engineering of UMG‐SP2 improves the understanding of polyurethane degradation mechanisms and generates enzyme ...

Molecular Dynamics Simulation of Sympathetic Crystallization of Molecular Ions [PDF]
, 2003 It is shown that the translational degrees of freedom of a large variety of molecules, from light diatomic to heavy organic ones, can be cooled sympathetically and brought to rest (crystallized) in a linear Paul trap. The method relies on endowing the molecules with an appropriate positive charge, storage in a linear radiofrequency trap, and ...
