Abstract
Photoregulated adenylate cyclases bPAC and OaPAC are compared using classical molecular dynamics simulations in both states, before and after blue light irradiation. The pathways of signal transduction from the photoreceptor to the catalytic domain are determined. The more pronounced acceleration of the catalytic reaction rate as a result of light irradiation in the case of bPAC is explained both by a shift in equilibrium towards a closed conformation and by a larger number of suboptimal pathways of allosteric signal transduction from photoreceptor to catalytic domain
