Hi Chris, Depending on your caps the monomers should be available to import directly into Coot and refine in refmac. You can find a full list of available monomers if you drill down in the ccp4 libraries directory. I'm guessing you may have and acetylated amino terminus which would be ACE.
Drop me another email if you can't find the list Joel -----Original Message----- From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.UK] On Behalf Of Chris BROWN (P53LAB) Sent: Friday, 22 June 2012 4:37 p.m. To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] Capping peptide Hi all I m just finishing the refinement of several peptide:protein complex structures and have become unstuck at modifying the N and C terminal ends (of the synthetic peptides) with the generic acetyl and amide capping groups respectively. Could some one please explain to me the most straight forward way of accomplishing this. regards Chris
