apologize for the silliness of the question. If the first amino acid of
your protein is a Glutamic acid, what would you set the protonation
status using the -ter option of pdb2gmx? The protein is in 0.1 molar
NaCl solution. I know it is basic Biochem, but I am a bit stumped here.<br></div>Thanks for the favor of a reply.</div></body></html>
