The use of free-energy landscapes rationalizes a wide range of aspects of protein behavior by providing a clear illustration of the different states accessible to these molecules, as well as of their populations and pathways of interconversion. The determination of the free-energy landscapes of proteins by computational methods is, however,... Read More

Recognition of the methyl-7-guanosine (m7G) cap structure on mRNA is an essential feature of mRNA metabolism and thus gene expression. Eukaryotic translation initiation factor 4E (eIF4E) promotes translation, mRNA export, proliferation, and oncogenic transformation dependent on this cap-binding activity. eIF4E–cap recognition is mediated via complementary charge interactions of the positively...

Protein degradation plays a critical role in cellular homeostasis, in regulating the cell cycle, and in the generation of peptides that are used in the immune response. The 20S proteasome core particle (CP), a barrel-like structure consisting of four heptameric protein rings stacked axially on top of each other, is... Read More

To provide high-resolution X-ray crystallographic structures of a peptide with the Trp-cage fold, we prepared a cyclized version of this motif. Cyclized Trp-cage is remarkably stable and afforded two crystal forms suitable for X-ray diffraction. The resulting higher resolution crystal structures validate the prior NMR models and provide explanations for experimental observations that could not be rationalized by NMR structural data,...

We introduce a new approach to improve structural and dynamical determination of large metalloproteins using solid-state nuclear magnetic resonance (NMR) with 1H detection under ultrafast magic angle spinning (MAS). The approach is based on the rapid and sensitive acquisition of an extensive set of 15N and 13C nuclear relaxation rates. The system on which we demonstrate these methods is the...

While information from homologous structures plays a central role in X-ray structure determination by molecular replacement, such information is rarely used in NMR structure determination because it can be incorrect, both locally and globally, when evolutionary relationships are inferred incorrectly or there has been considerable evolutionary structural divergence. Here we describe a method that...

Despite advances in resolution accompanying the development of high-field superconducting magnets, biomolecular applications of NMR require multiple dimensions in order to resolve individual resonances, and the achievable resolution is typically limited by practical constraints on measuring time. In addition to the need for measuring long evolution times to obtain high resolution, the need to distinguish the sign of the frequency...

Allostery is a fundamental mechanism of regulation in biology. The residues at the end points of long-range allosteric perturbations are commonly identified by the comparative analyses of structures and dynamics in apo and effector-bound states. However, the networks of interactions mediating the propagation of allosteric signals between the end points often remain elusive. Here we show that the covariance analysis of NMR chemical...
