Hi Senal,

I don't think GLYCAM has parameters for cyano group.  I suggest that you use gaff for cyanogenic moiety.  You also need atomic charges for your molecules.  Please check GLYCAM06 paper for procedures  to derive charges for molecules in GLYCAM06.

Best regards,

Subject: Simulating cyanogenic glucoside

Dear GLYCAM users,

I have been trying to simulate a cyanogenic glucoside (linamarin) bound protein with AMBER. Since GLYCAM doesn't offer parameters for a cyanogenic moiety I renamed the sugar portion as "0GB" to comply with GLYCAM residue naming and the rest of the ligand "UNK". But so far I was unable to generate parameters for the entire system successfully. Am I following a correct approach? I appreciate any guidance on handling this matter

Thank you
