Re: [ccp4bb] Dealnig with O-linked mannose

Thank you all for helpful suggestions. My question was how to properly connect a mannose to a serine and real-space refine the result. My apologies for not being clear enough. Coot can't find MAN-SER or SER-MAN in it's library (Coot 0.7.1, mon_lib 5.41) It does not automatically make the bond

Hi Dmitry, I think the best way is not to make a new monomer. MAN-SER and MAN-THR linkages do exist in the ccp4 monomer lib. If you simply build a mannose with its O1 removed and put the C1 ~1.4 Angstrom to the OG of the serine I think refmac should be able to detect the linkage. When this
