Homology modelling
Pfrag
This service gives access to the Pfrag homology modelling program. Pfrag uses the segment matching method to insert fragments of structure, taken from a database of high quality structures. The mathing is based on local sequence similarity, van der Waals contacts and a RMSD superposition.
The program takes two inputs, an alignment and one template structure. The format of the alignment is the following:
>Name of target sequence
One letter residue sequence
>Name of template sequence
One letter template sequence
