From: Red light-induced structure changes in phytochrome A from Pisum sativum
Right panel shows normal mode motions with the lowest energy in subunit A in the crystal structure (left panel) of PSM of A. thaliana phyB. The 3-times magnified amplitudes of the motions of Cα atoms are illustrated by colored sticks, which indicate the directions of the motions from the yellow to blue ends. The motions of domains are schematically indicated by arrows. The cutoff distance used in the normal mode calculation was 7 Å.
