Visual Analysis

Calculations performed over the first 10 non-trivial modes of the molecule.

Deformation Energy provides a measure for the amount of local flexibility in the protein.

Atomic Fluctuation provides the amplitude of the absolute atomic motion.

Deformation Energies
Atomic Fluctuation

The magnitute of the deformation/fluctuation is represented by thin to thick tube colored blue (low), white (moderate) and red (high).

Dynamical Cross-Correlation Map (DCCM)


All modes were used to calculated the residue cross-correlation.


Correlation map revealing correlated (red) and anti-correlated (blue) regions in the protein structure.

Assuming: Cab = Correlation between residues a and b

If Cab = 1 the fluctuations of residues A and B are completely correlated (same period and same phase), if Cab = -1 the fluctuations of residues a and b are completely anticorrelated (same period and opposite phase), and if Cab = 0 the fluctuations of a and b are not correlated.
