Implementation of a six-dimensional search using the AMoRe translation function for difficult molecular-replacement problems

S. Sheriff, H. E. Klei and M. E. Davis

Abstract: A six-dimensional molecular-replacement procedure has been implemented using Perl scripts and the CCP4 version of the translation function of the molecular-replacement program AMoRe. These tools have allowed the structure determination of CTLA-4 monomer from NMR-derived coordinates, and of a potential complex of MurD with a substrate. In both cases other molecular-replacement programs, X-PLOR and AMoRe, when used in a conventional manner, either failed or did not yield an obvious solution.
