Many [[X-ray crystallography|crystallographic]] structures have missing loops -- that is, ranges of amino acids with no [[atomic coordinate file|atomic coordinates]] in the model. These "gaps" in the model are often thought to be artifacts of inadvertant disorder in the crystal. In some cases, these gaps may be alerting us to the presence of intrinsically disordered loops in an otherwise folded protein. Such gaps are the basis for the [[#Protein disorder predictors|DISOPRED2 disorder prediction server]]. [[FirstGlance in Jmol]] offers [[Temperature_value#Missing_Residues|one method for locating and visualizaing such gaps]]. | Many [[X-ray crystallography|crystallographic]] structures have missing loops -- that is, ranges of amino acids with no [[atomic coordinate file|atomic coordinates]] in the model.
