Specific structural damage inflicted on a cryocooled crystal of apoferritin during sequential data sets collected on beamline ID14-4 at ESRF. (a) 2Fo − Fc map of Glu63 contoured at 0.2 e Å−3 after a dose of 2.5 MGy and (b) after 50 MGy. (c) 2Fo − Fc map of Met96 contoured at 0.2 e Å−3 after a dose of 2.5 MGy and (d) after 50 MGy, showing loss of electron density around the disordered atoms (Garman & Owen, 2006). |
