Crystal Structure of Gadolinium derivative of HEWL solved using Free-Electron Laser radiationCrystal Structure of Gadolinium derivative of HEWL solved using Free-Electron Laser radiation
Structural highlights
Function[LYSC_CHICK] Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has bacteriolytic activity against M.luteus.[1] Publication Abstract from PubMedX-ray free-electron lasers (XFELs) show great promise for macromolecular structure determination from sub-micrometre-sized crystals, using the emerging method of serial femtosecond crystallography. The extreme brightness of the XFEL radiation can multiply ionize most, if not all, atoms in a protein, causing their scattering factors to change during the pulse, with a preferential 'bleaching' of heavy atoms. This paper investigates the effects of electronic damage on experimental data collected from a Gd derivative of lysozyme microcrystals at different X-ray intensities, and the degree of ionization of Gd atoms is quantified from phased difference Fourier maps. A pattern sorting scheme is proposed to maximize the ionization contrast and the way in which the local electronic damage can be used for a new experimental phasing method is discussed. Towards phasing using high X-ray intensity.,Galli L, Son SK, Barends TR, White TA, Barty A, Botha S, Boutet S, Caleman C, Doak RB, Nanao MH, Nass K, Shoeman RL, Timneanu N, Santra R, Schlichting I, Chapman HN IUCrJ. 2015 Sep 30;2(Pt 6):627-634. eCollection 2015 Nov 1.
