Maximum Occurrence (MO) refers to a method for making rigorous numerical assessments on the conformational space of flexible biological macromolecules^[1]. The Maximum Occurrence is the maximum percent of time that a macromolecule can spend in a given conformation and still be compatible with the experimental data (see Figure).

Maximum Occurrence profiles for some conformers of Calcium-loaded calmodulin. Dashed line indicates the maximum disagreement within experimental and calculated data.

Case Study: Calmodulin

Maximum Occurrence profiles were calculated for N60D Calmodulin^[2]. Calmodulin is a two-domain protein experiencing high mobility in the central region.^[3][4] (PDB ENTRIES 1sw8,2k0j,2k61)
