CX

Protrusion index
Web server
 
Welcome to the CX server!
This server calculates the atomic Protrusion Index from a three-dimensional protein structure.
The method is explained in:

Pintar A., Carugo O. and Pongor S, CX, an algorithm that identifies protruding atoms in proteins., Bioinformatics 2002 Jul;18(7):980-4

Please cite the above reference if you publish results obtained using this server.
 
To run the calculation, submit a PDB file containing a single structure. Please see help and guidelines on how to prepare your input file BEFORE you try to submit anything!
Optional parameters
radius of the sphere (angstrom)
average atom volume (cube angstrom)
calculate mean CX per residue
