FEATURES AND FUNCTION:
=====================
ADSBET performs following steps for computation of net as well as component energy terms
-- Determination of residue specific salt-bridges or ion-pairs from crystal structures
-- Determination of protein specific center of mass; needed for desolvation energy computation
-- Determination of protein specific grid points (along x, y and z dimension) to be used in APBS calculation
-- Preparation of PQR (protein charge-radius) file from pdb file (using PDB2PQR)
-- generation of hydrophobic isosteres mutated PQR files (5 per salt bridge )
These are needed for computation of electrostatic field energy
-- Preparation of APBS input file using modified PQR file plus user, default and generated parameters.
-- run of APBS and computation of component energy terms
-- Redirection of all energy terms in compact excel format
INPUT:
=====
Cryatal structure in PDB format (RCSB)
If minimized user to keep all header info as is the original PDB.
OUTPUT:
======
one compact output named "all_sb_eng_table.xls" in the working directory
PLATFORM
========
The program works in any UNIX environment including CYGWIN. It is extensively tested to function properly
from CYGWIN environment.
INSTALLATION:
============
THE PROGRAM IS EXTENSIVELY TESTED TO FUNCTION ON CYGWIN WITH both in C-SHELL/B-SHELL
1. Download ADSBET ("ADSBET.zip") from its home page -- << sourceforge.net >>
2. unzip the content - README (this file) and "WORK"-directory will be
visible with sample pdb & pqr files (1CZP.pdb,1CZP.pqr)
3. Open a Shell (C- or B-SHELL in CYGWIN) and 'cd' to "WORK" directory of "adsbet.exe"
4. In SHELL prompt type "./adsbet.exe h" OR "./adsbet.exe"
INSTALLATION OF OTHER PROGRAMS NEEDED for ADSBET
===================================================
1. ADAPTIVE POISSON-BOLTZMAN SOLVER ie "APBS v1.4" to be installed/unzipped in the defined directory:
DIRECTORY: "program-working-directory/afp/apbs"
[available at : http://sourceforge.net/projects/apbs/files/apbs/apbs-1.4.0/ ]
2. "PDB2PQR v1.9" to be installed/unzipped in the defined directory
DIRECTORY: "program-working-directory/afp/pqr
[available at : http://sourceforge.net/projects/pdb2pqr/files/pdb2pqr/pdb2pqr-1.9.0/ ]
NOTE: ADSBET USE SBION AND SBION2 FOR EXTRACTION OF ATOMIC AND RESIDUE SPECIFIC SALT BRIDGES
FROM CRYSTAL STRUCTURE. IT ALSO USED THE SAID PROGRAMS FOR CORRECTION OF PDB FILES EXCLUSIVELY
NEEDED FOR CORRECTNESS OF ENERGY TERMS. USERS ARE REQUIRED TO CITE THESE FOR THEIR USE OF ADSBET.
IMPORTANT CITATIONS:
==================
NOTE : The program ADSBET use "APBS v1.4 (binary)", "PDB2PQR v1.9 (binary)"
and "SBION2"/"SBION" for proper functioning ;
Users of ADSBET are needed to cite following references for their work:

=========================================================================================
ENERGY MINIMIZATION OF PDB FILES:
================================
SALT BRIDGE ENERGY-TERMS GIVE BEST RESULT WHEN PDB STRUCTURE FILES ARE
SUBJECTED TO ENERGY MINIMIZED. THIS STEP HAS TO BE DONE WITH CAUTION.
HELIX and SHEET INFORMATION ARE TO BE RETAINED in MINIMIZED FILE AS ORIGINAL
PDB FILES.
FEEDBACK:
========
Encouragement, suggestions, bug reports, and constructive criticism
may be sent to akbanerjee[at]biotech[dot]buruniv[dot]ac[dot]in;. we will do our best
to reach with possible solution as sooner as we can.
