Identifying native-like protein structures with scoring functions based on all-atom ECEPP force fields, implicit solvent models and structure relaxation.

29 Sep 2009 Availability of energy functions which can discriminate native-like from non-native protein conformations is crucial for theoretical protein structure prediction and refinement of low-resolution protein models. This article reports the results of ... Read more...

Channel-forming solvates of 6-chloro-2,5-dihydroxypyridine and its solvent-free tautomer 6-chloro-5-hydroxy-2-pyridone.

28 Sep 2009 On crystallization from CHCl3, CCl4, CH2ClCH2Cl and CHCl2CHCl2, 6-chloro-5-hydroxy-2-pyridone, C5H4ClNO2, (I), undergoes a tautomeric rearrangement to 6-chloro-2,5-dihydroxypyridine, (II). The resulting crystals, viz. 6-chloro-2,5-dihydroxypyridine ... Read more...

Tryptophan conformations associated with partial unfolding in ribonuclease T1.

14 Sep 2009 The origin of the biexponential fluorescence decay of Trp in ribonuclease T1 under mildly destabilizing conditions, such as increased pH or temperature, or the presence of detergent, is still not understood. We have performed two extended ... Read more...
