Dear amber friends,
I am trying to do minimization in implict solvent by GBSA method ( igb=5)
for a zinc protein complex. i used zinc and histidince force fields from
http://www.pharmacy.manchester.ac.uk/bryce/amber.
When i did the minimization and simulation in explicit environment, it goes
well. While i am trying to do GBSA minimization (200 steps) the histidine
side chain atoms moves 10A away from each other, therefore van der Waals and
bond energy reached unprintable limits. I would like to know how to do GBSA
or PBSA minimization and simulation for zinc-protein complex.
i am eagerly waiting for reply.
