Re: CCL:Adding counterions on a protein




Hello Sandro,

There are many scripts in Accelrys' on-line BCL script library for use with Insight II.  One of these scripts is called counterion.bcl.  This script will place counterions suitable for use with several different force fields for charged residues in RNA/DNA or PEPTIDES.  The script uses a template recognition method to determine a suitable initial placement.  Additional recognition templates can be added.  Be sure to read the scripts header information closely for any dependant scripts that will need to be downloaded with it.  The main script's name is counterion.bcl.  The link is

Best wishes,

Ken

CCL:Adding counterions on a protein





Dear All
Does anybody know if there is an efficient script to add counterions on
a protein in a random way?
Actually, I tried to perform it with InsightII and Sybyl scripts but they
have been constructed for nucleotides. Would it be possible to get scripts
properly modified for proteins working with InsightII or Sybyl programs?
Thanks in advance for your help.
Best regards
Sandro
