It is not uncommon for a surface loop of the crystallized protein to be disordered. Often such loops are [[intrinsically disordered]]. The disorder blurs the electron density map for that loop, and the loop residues are not given coordinates in the model: they are missing in the model. However, they were not missing in the crystallized protein. | It is not uncommon for a surface loop of the crystallized protein to be disordered.
