Overview
DisplacementMap is made for easy investigations of suitable positions for site-directed mutagenesis of amino residues into cysteines and FRET/EPR pair labelling.
A Open and Closed form of a protein should be loaded. New objects should be created for the selected asymmetric unit. Parts of the protein should be aligned, leaving the flexible part in two different positions.
The input is the objects, Open (molecule1) and Closed (molecule2).
Further is the criteria for selecting which atom the distance should be calculated between. Standard is atom='CA' (atom).
Then one selects the Förster distance R0 (mindist). This is the minimum distance between the residues. This depends of the selection of the FRET pair and protein at hand. But usually in the range 40 - 80 Angstrom is suitable.
Then one defines the minimum displacement that is accepted. Usually ..→
