Abstract
We obtained a solution structural model of myoglobin (Mb) formed upon the CO photolysis of MbCO by analyzing time-resolved X-ray solution scattering data. An experiment-restrained rigid-body molecular dynamics simulation was used to find the best model whose theoretical difference scattering curve gives a satisfactory agreement with the experimental data at the time delay of 10 ns. The obtained solution model shows structural changes similar to crystallographic models for MbCO →Mb but also displays a noticeable difference in that the N-terminus and F helix show larger structural changes.
