X-ray crystallography has been applied to the structural analysis of a series of tetrapeptides that were previously assessed for catalytic activity in an atroposelective bromination reaction. Common to the series is a central Pro-Xaa sequence, where

An entirely new type of chalcogenide cluster and a new structural mechanism for the formation of large semiconducting tetrahedral clusters have been revealed as a result of crystallization of a templated indium sulfide consisting of an unprecedented

Synthetic biology and systems chemistry demonstrate a growing interest in modified nucleotides to achieve an enzymatically stable artificial nucleic acid. A potential candidate system is xylose-DNA, in which the 2'-deoxy-beta-D-ribo-furanose is subst

De novo designed peptides, capable of undergoing a thermally triggered beta-strand-swapped self-assembly event leading to hydrogel formation were prepared. Strand-swapping peptide 1 (SSP1) incorporates an exchangeable beta-strand domain composed of e

The majority of protein structures are determined in the crystalline state, yet few methods exist for the characterization of dynamics for crystalline biomolecules. Solid-state NMR can be used to probe detailed dynamic information in crystalline biom

A disulfide-bridged two-stranded α-helical coiled-coil peptide has been designed which undergoes a random coil to α-helical transition at pH 7 and 20 °C upon metal binding to two sites engineered into the molecule. The metal binding coiled-coil, d

The two available crystallographic structures of cobalamin dependent enzymes, the 27 kDa fragment of the methylcobalamin-dependent enzyme, methionine synthase, from Escherichia coli [Drennan, C. L. et al. Science 1994, 266, 1669] and the 5‘-deoxyad

The application of a recently developed technique of conformational memories (Guarnieri, F.; Wilson, S. R. J. Comput. Chem. 1995, 16, 5, 648) to the study of peptide structure is illustrated with an analysis of the conformational populations of the d
