The heterogeneity in a protein crystal revealed by synchrotron radiation

The heterogeneity in a single crystal of hydrogenase has been recognized using synchrotron radiation. This heterogeneity has been estimated from five different positions of the crystal by analyzing the number of significant reflections above background levels and the mosaicity of the diffraction spots. The crystal showed the highest degree of mosaicity at one end of the crystal, the initial point of crystal growth. The degree of mosaicity...
