Model types to represent conformational heterogeneity. (a) Examples of the multiple conformations of protein side chains captured by cryoEM and X-ray crystallography. (b) Ensemble representation of a Lys side chain. (c) Multiconformer representation of a Lys side chain. (d) One-state NMR ensemble from distant restraints and a two-state NMR ensemble from CEST data. (e) 3D classification from cyroEM results in different but related maps, often with distinct associated models.
