[gmx-users] glutamic acid protonation

[quantrum75]

Hi group.
I am having a sudden brainfart here and 
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.
Thanks for the favor of a reply.
