Laboratory of Biomolecular Structure and Function

The Laboratory of Biomolecular Structure and Function (LBSF) was created in 2015 to serve scientists of Oklahoma City, in particular OUHSC and OMRF, that are interested in structural aspects of their macromolecular targets.The LBSF is part of the OUHSC Vice President Research Core Facilities. LBSF was created on the basis of the Macromolecular Crystallography Laboratory of the Department of Biochemistry and Molecular Biology. This earlier lab was created in 1998 and became a core facility for the  Oklahoma Center of Biomedical Research Excellence (CoBRE) in Structural Biology (OCSB). The LBSF is one of two sites that make up the Biomolecular Structure Core of the OCSB. The other site is the Macromolecular Crystallography Laboratory (MCL) at OU-Norman. Users of the LBSF also have access to the MCL which a complementary set of instruments. 

The LBSF is equipped with modern crystallographic equipment and computers: A 2015 Rigaku 007 generator, R-axis IV and Mar345 image plate detectors, Osmic mirrors on both ports, Rigaku and Oxford Systems crystal cooling systems. The R-AXIS IV has an optional helium path for working with large unit cells. 

D-TrekXDSMosflm and HKL2000 image processing software are available for data processing, Any of the PhenixCCP4CNS program suites can be used for structure determination and refinement, while COOTChimera and Molmol are offered for graphical representation of the results. 

The LBSF has a 2014 Wyatt plate reading dynamics light scattering instrument that enables high-throughput data collection with no user intervention for evaluation of the oligomerization states of  proteins. Monodisperse solutions with 5-20 mg/ml of protein are required for crystallization experiments, small angle x-ray scattering experiments, and cryo electron microscropy (cryo-EM) experiments. 

The LBSF has a 2019 Leica cryo-plunger for the preparation of cryo-grids for cryo-EM work. 

200 microliters of 95% pure protein sample at a concentration of 5-20 mg/ml are needed to set up ten 96-well trays with the 2018 Art Robbins Gryphon LCP crystallization robot. The robot can also set up crystallization experiments in the lipidic cubic phase for the crystallization of membrane proteins.


Laboratory provides following services:

  • Advice on protein construct design, expression, and purification
  • Help with protein purification (BRC 406)
  • Dynamic light scattering data collection and analysis
  • Help with Small-angle X-ray Scattering experiments (Dr. Mooers)
  • Help with preparing grids for electron microscopy work.
  • Crystallization set up with crystallization robot for high throughput screening with sparse matrics
  • Crystallization set up by robot or manually for crystal size optimization 
  • Protein-ligand co-crystallization
  • Crystal soaking experiments
  • Scoring crystallization drops by light microscopy
  • Screening crystals for X-ray diffraction quality
  • Optimization of cryo protectant solutions
  • On-site X-ray data collection, processing, and evaluation
  • Remote X-ray data collection at synchrotron radiation at SSRL
  • On-site collection of Small Angle X-ray Scattering data at SSRL
  • Structure determination, refinement, and structure analysis
  • Design of mutant proteins based on structural information
  • Preparation of figures for grant applications and publication
  • Molecular modeling and structure-based drug design (Dr. Tim Mather)
