Dear all, I am seeing some bulk extra denisty near my protein molecule, in a 2.7 angstrom map. The crystallization condition condition has a sulfated polysaccharide. If I want to perform a MR with this polysaccharide, in presence of the refined protein model in the cell, which program should I use?. In the phaser, there are options only for proteins and nucleic acids. Is there, any automated ligand identifying/fitting program that can work at this resolution? All suggestions are wellcome. Thanks in advance. warm regards, Murugan
