Quantum effects investigated on the dynamics of a protein
There is a growing number of indications that quantum mechanics might play a role for the functioning of certain biomolecules and within living cells, as for instance through tunnelling effects or quantum entanglement. However, not much is reported in the literature about experimental results, certainly because the expected effects are rather small. As quantum effects depend on the mass of the scatterer, their signature should be detectable when comparing a protonated protein with its per-deuterated counterpart. We propose therefore to study Green fluorescent protein (GFP) in the two versions, at very low temperature where these effects should be highest, but also by doing a temperature scan for elastic scattering and recording the density of states and QENS at low, intermediate and high temperature to permit data analysis within a newly developed approach taking into account quantum effects.
