One, cyclophilin A, can facilitate protein folding, while the other, dihydrofolate reductase (dhfr), helps regulate cell proliferation and cell growth. Their method, for the first time, provides an atomically detailed structural framework for the dhfr ...

The earliest clue was that some protein segments didn't show up in X-ray crystallography or NMR studies, the standard ways of studying protein structure. By the 1990s people who studied how proteins interact with DNA had noticed the proteins often ...

4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins
4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins
Abstract A pair of 4D NMR experiments for the backbone assignment of disordered proteins is presented. The experiments exploit 13C direct detection and non-uniform sampling of the indirectly detected dimensions, and provide correlations of the aliphatic proton (Hα, and Hβ) and carbon (Cα, Cβ) resonance frequencies to the protein backbone. Thus, all the chemical shifts regularly used to map the transient...

A strong 13C chemical shift signature provides the coordination mode of histidines in zinc-binding proteins
A strong 13C chemical shift signature provides the coordination mode of histidines in zinc-binding proteins
Abstract Zinc is the second most abundant metal ion incorporated in proteins, and is in many cases a crucial component of protein three-dimensional structures. Zinc ions are frequently coordinated by cysteine and histidine residues. Whereas cysteines bind to zinc via their unique Sγ atom, histidines can coordinate zinc with two different coordination modes, either Nδ1 or Nε2 is coordinating the zinc ion. The determination of this coordination mode is crucial for the accurate...

The two-body Slowly Relaxing Local Structure (SRLS) model was applied to (15)N NMR spin relaxation in proteins and compared with the commonly used original and extended model-free (MF) approaches. In MF, the dynamic modes are assumed to be decoupled, local ordering at the N-H sites...
