Solution and crystal phase resonance Raman spectroscopy: Valuable tools to unveil the structure and function of heme proteins

In the present review, examples are provided illustrating the application of resonance Raman microscopy to heme protein single crystals to highlight the artifacts induced by the crystallization process or the conformational alteration induced by cooling. Moreover, the structural information determined from the RR spectra of heme proteins in solution and crystals is compared to that obtained from their X-ray structures to show how the combined...
