Phenix refine chain breaks
WebFigure 5c shows that the mean length of chains built using phenix.map_to_model version 2 is greater than those built with version 1, with a mean chain length of 23 for version 2 and 16 for version 1. The longer chain length means that the resulting model has fewer chain breaks and will require fewer choices during sequence alignment. Webrigid-body-refined against the various maps. You can use the phenix tool phenix.dock_in_map to place the chains in each map if you have not done it in some other way. Once a set of models has been set up to match the maps, the map-model correlation in the region of each chain in each model is calculated. This

WebThe Phenix atom selection syntax. Many of the programs in Phenix, and phenix.refine in particular, allow (or require) you to specify selections of atoms in a model. Common examples include: TLS (constrained anisotropic displacement) and rigid-body refinement groups. Selections for isotropic versus anisotropic B-factor refinement. Atoms to leave ... Webmoderate resolution using main-chain hydrogen bonds as well as side-chain–side-chain and side-chain–main-chain hydrogen bonds. We have added automatic generation of distance restraints for hydrogen bonds in protein and nucleic acid secondary structures, which can help to enforce correct geometry at lower resolution.
