1. Breathing motion of myoglobin: the superposed Mb structures before laser illumination (orange) and after 750 min of laser illumination (yellow) at 140 K are shown, with emphatic coordinates (green and cyan) of gating motion of amino acid residues.
Breathing motion of myoglobin: the superposed Mb structures before laser illumination (orange) and after 750 min of laser illumination (yellow) at 140 K are shown, with emphatic coordinates (green and cyan) of gating motion of amino acid residues. Emphatic coordinates are calculated from the coordinates of Mb before and after laser irradiation at 140 K. Xemphatic1=X750min+ΔX, Xemphatic2=X750min+2ΔX, ΔX=X750min–XLaseroff. Here, XLaseroff and X750min are atom coordinates of before-laser illumination and after 750 min of laser illumination at 140 K. The surfaces of the internal cavities are shown by the mesh. The movements of amino acid residues between the cavities are shown by white arrows.
