Refinement crystallography
WebThe characterization of the three-dimensional structure of solids is of major importance, especially in the pharmaceutical field. In the present work, NMR crystallography methods … WebAltwyk Altwyk is a stand-alone program which produces the general position and Wyckoff positions for any space group symbol listed in International Tables for Crystallography, Vol. A (1983). Altwyk can currently process over 1,000 of them, probably covering all actual literature cases, but we are still implementing new odd symbols.

Diffraction data of mutant S12A and its complex were collected at a wavelength of 1.96 Å and 1.73 Å respectively using a Cµ MSC PAD200sk detector. All data were indexed, processed and scaled using the programme DENZO and SCALEPACK from HKL 3.0 package (Otwinowski and Minor 1997).
