Fig. 5: The FAD and ATP-binding site opening distances for the apo and holo ACOX-1.1 MD simulations.

a, b The size of the FAD and ATP-binding site openings for each system, plotting (a) the size of the ATP opening on subunit A versus the size of the ATP opening on subunit B and (b) the size of the FAD opening on subunit A versus the size of the FAD opening on subunit B. The systems included apo ACOX-1.1, holo ACOX-1.1, apo ACOX-1.1 replicating the waters from subunit A for both subunits, and apo ACOX-1.1 replicating the waters from subunit B for both subunits. A plot was done for each system for 10 MD simulationsā2āμs each (first row), 20 MD simulationsā2āμs each (second row) or 20 MD simulationsā4āμs each (third row).
