[gmx-users] polymer state

[hosein geraili]

Dear all,
How can I find the polymer state (monomer, dimer, trimer, ...?) of a protein? I thought it would be the REMARK 350 AUTHOR DETERMINED BIOLOGICAL UNIT in the pdb file,but for a protein, I read in its article that it is monomer in solution, and this REMARK was HEXAMERIC!!!I need to simulate some proteins, but I can't find their state in their main article.
