The facility houses state-of-the-art instrumentation for X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and cryo-electron microscopy (cryo-EM), each offering unique advantages for structural determination.

X-Ray Crystallography

X-ray crystallography is a key method for determining atomic-resolution structures of biomolecules, particularly proteins and nucleic acids. NYSBC offers high-intensity X-ray sources, including synchrotron beamlines, to enhance data collection efficiency and resolution. Automated crystallization robots optimize crystal growth conditions, increasing the chances of obtaining high-quality diffraction data. Once crystals are prepared, advanced diffractometers with fast-readout detectors enable rapid data acquisition.

This technique is essential for understanding enzyme mechanisms, ligand binding, and conformational changes in biomolecules. It has been instrumental in drug discovery, enabling precise design of small molecules that target disease-related proteins. However, the method requires well-ordered crystals, which can be a limitation for flexible or membrane-associated proteins. To address this, NYSBC provides microfocus beamlines and in situ diffraction screening to improve data collection from challenging samples.

NMR Spectroscopy

NMR spectroscopy is a powerful tool for studying biomolecular structures in solution, providing insights into dynamic processes that are difficult to capture with crystallography. NYSBC houses high-field NMR spectrometers, including 900 MHz instruments, which enhance spectral resolution and sensitivity. These systems are particularly useful for investigating protein-ligand interactions, conformational flexibility, and molecular dynamics in physiologically relevant conditions.

A key advantage of NMR spectroscopy is its ability to analyze macromolecules without requiring crystallization, making it ideal for studying intrinsically disordered proteins and transient complexes. Researchers at NYSBC use multidimensional NMR techniques to assign chemical shifts, measure interatomic distances, and determine secondary and tertiary structures. The facility also supports isotope labeling strategies to improve signal detection for large proteins and nucleic acids. While NMR has molecular size constraints, advancements in cryogenic probes and non-uniform sampling methods have expanded its applicability to larger biomolecular assemblies.

Cryo-Electron Microscopy

Cryo-electron microscopy (cryo-EM) has revolutionized structural biology by enabling near-atomic resolution visualization of macromolecular complexes without requiring crystallization. NYSBC is equipped with cutting-edge cryo-EM instruments, including direct electron detectors and high-throughput automated sample preparation systems, allowing researchers to capture structural snapshots of proteins, ribosomes, and viral particles in their native states.

Single-particle cryo-EM is particularly valuable for studying large and flexible biomolecules that are difficult to crystallize. The facility provides access to high-end microscopes such as the Titan Krios, which offers high-resolution imaging through phase plate technology and energy-filtered electron detection. Additionally, NYSBC supports cryo-electron tomography, enabling three-dimensional reconstruction of cellular structures and providing insights into macromolecular organization within biological systems. Machine learning algorithms enhance image processing, improving resolution and accuracy in structural studies.
