X-ray Pulses Yield Protein And Metal Data
The study of metal-containing proteins, such as the complex that mediates the light reaction in photosynthesis, has a new tool: Femtosecond X-ray pulses facilitate simultaneous diffraction and spectroscopy analyses of metalloproteins, enabling study of radiation-sensitive, difficult-to-crystallize systems at room temperature (Science, DOI: 10.1126/science.1234273). The approach will promote time-resolved chemical dynamics studies of metalloproteins, say research team leaders Vittal K. Yachandra and Junko Yano of Lawrence Berkeley . . .
