[ccp4bb] molecular replacement solution

2011-03-15 Thread Careina Edgooms
Dear CCP4 members I have a confusion with molecular replacement. I wish to solve a monomeric protein in P21 where there are 2 monomers in asymmetric unit. I have a search model that also has 2 monomers in asymmetric unit. First I try using Phaser. I use only one chain of the monomer model

Is there NCS? (How's the self rotation look? How about the native patterson?) Does your search model have flexible loops? You may have the right solution, but the flexible loops may be in a different conformation and cause clashes. Trim the search model to the conserved / structured
