The Protein Data Bank (PDB) is the single global archive of experimentally determined three-dimensional (3D) structure data biological macromolecules. Since 2003, PDB has been managed by Worldwide (wwPDB; wwpdb.org), an international consortium that collaboratively oversees deposition, validation, biocuration, and open access dissemination 3D macromolecular data. Core Archive houses atomic coordinates more than 144 000 structural models proteins, DNA/RNA, their complexes with metals small...
SUMMARY Maximum entropy (ME) inversion is a non-linear technique for inverse problems where the object to be recovered known positive. It has been applied in areas ranging from radio astronomy various forms of spectroscopy, sometimes with dramatic success. In some cases, ME attained an order magnitude finer resolution and/or smaller noise level than that obtainable by standard linear methods. The successes all seem occur cases ‘nearly black‘: essentially zero vast majority samples. We show...
The Biological Magnetic Resonance Data Bank (BMRB, https://bmrb.io) is the international open data repository for biomolecular nuclear magnetic resonance (NMR) data. Comprised of both empirical and derived data, BMRB has applications in study biomacromolecular structure dynamics, interactions, drug discovery, intrinsically disordered proteins, natural products, biomarkers, metabolomics. Advances including GHz-class NMR instruments, national trans-national cyberinfrastructure, hybrid...
In January 2020, a workshop was held at EMBL-EBI (Hinxton, UK) to discuss data requirements for deposition and validation of cryoEM structures, with focus on single-particle analysis. The meeting attended by 45 experts in processing, model building refinement, validation, archiving such structures. This report describes the workshop's motivation history, topics discussed, consensus recommendations resulting from workshop. Some challenges future methods-development efforts this area are also...
NMR spectroscopy is one of the most powerful and versatile analytic tools available to chemists. The discrete Fourier transform (DFT) played a seminal role in development modern NMR, including multidimensional methods that are essential for characterizing complex biomolecules. However, it suffers from well-known limitations: chiefly difficulty obtaining high-resolution spectral estimates short data records. Because time required perform an experiment proportional number samples, this problem...
The Protein Data Bank (PDB) is the global repository for public-domain experimentally determined 3D biomolecular structural information. archival nature of PDB presents certain challenges pertaining to updating or adding associated annotations from trusted external biodata resources. While each Worldwide (wwPDB) partner has made best efforts provide up-to-date annotations, accessing and integrating information disparate wwPDB data centers can be an involved process. To address this issue,...
NMR spectroscopy is an inherently insensitive technique, and many challenging applications such as biomolecular studies operate at the very limits of sensitivity resolution. Advances in superconducting magnet, cryogenic probe, pulse sequence technologies have resulted dramatic improvements both resolution past decade. Conversely, signal-processing method used most widely spectroscopy, extrapolation time domain signal by linear prediction (LP) followed discrete Fourier transformation (DFT),...

We report dramatic sensitivity enhancements in multidimensional MAS NMR spectra by the use of nonuniform sampling (NUS) and introduce maximum entropy interpolation (MINT) processing that assures linearity between time frequency domains NUS acquired data sets. A systematic analysis resolution 2D 3D reveals with NUS, at least 1.5- to 2-fold enhancement can be attained each indirect dimension without compromising spectral resolution. These are similar or higher than those newest-generation...
Many information-rich multidimensional experiments in nuclear magnetic resonance spectroscopy can benefit from a signal-to-noise ratio (SNR) enhancement of up to about 2-fold if decaying signal an indirect dimension is sampled with nonconsecutive increments, termed nonuniform sampling (NUS). This work provides formal theoretical results and applications resolve major questions the scope NUS enhancement. First, we introduce Sensitivity Theorem which any decreasing density applied...
Although the discrete Fourier transform played an enabling role in development of modern NMR spectroscopy, it suffers from a well-known difficulty providing high-resolution spectra short data records. In multidimensional experiments, so-called indirect time dimensions are sampled parametrically, with each instance evolution times along via separate one-dimensional experiments. The required to conduct experiments is directly proportional number sampled. Despite remarkable advances resolution...
