Dear glycobiologists and phenixfriends. I am trying to refine a NAG-NAG chain attached to an Asn122 in my (pentameric) structure. What is the proper description in the cif_link.params that is the equivalent of the pdb description pasted below that phenix so kindly ignores? Also, what is the proper way to define the cif_link.params file in the GUI? Thank you. -Chris LINK ND2 ASN A 122 C1 NAG A 834 1555 1555 1.37 LINK O4 NAG A 834 C1 NAG A 835 1555 1555 1.43 LINK ND2 ASN B 122 C1 NAG B 834 1555 1555 1.37 LINK O4 NAG B 834 C1 NAG B 835 1555 1555 1.43 LINK ND2 ASN C 122 C1 NAG C 834 1555 1555 1.37 LINK O4 NAG C 834 C1 NAG C 835 1555 1555 1.43 LINK ND2 ASN D 122 C1 NAG D 834 1555 1555 1.37 LINK O4 NAG D 834 C1 NAG D 835 1555 1555 1.43 LINK ND2 ASN E 122 C1 NAG E 834 1555 1555 1.37 LINK O4 NAG E 834 C1 NAG E 835 1555 1555 1.43 --------------------------------------------------- Chris Ulens, Ph.D. Lab of Structural Neurobiology Department of Molecular Cell Biology Campus Gasthuisberg, ON1 Herestraat 49, PB 601 B-3000 Leuven Belgium e [email protected] t +32 16 345812 f +32 16 345699 w http://www.xtal.be
