Allen Orville


Research Interests
• Structural basis of enzyme reaction mechanisms; protein crystallography; spectroscopy
• Systems biology at the microbe – plant interface, especially symbiotic N2-fixation by rhizobia within root nodules of leguminous plants
• Serial micro-crystallography with acoustic droplet ejection methods at synchrotron and free electron laser x-ray sources
• Oxygen activation and reactivity in solution, and in low temperature crystals; methods for poising and promoting enzyme reactions in crystals
• Single-crystal (polarized) electronic absorption and (polarized) resonance Raman spectroscopies correlated with x-ray crystallography from the same sample
