[gmx-users] energy minimization of protein taken from PDB

[md kashif]

Dear all
I have downloaded a protein from RCSB, having two chains. In order to go
for energy minimization should I delete one chain as both are similar and
other molecules like SO4, water etc? Is the protein having chain A only can
be used for energy minimization  using tutorial
