Comment on “Main role of fractal-like nature of conformational space in subdiffusion in proteins”

Maggi and Orozco [Phys. Rev. E 109, 034402 (2024)10.1103/PhysRevE.109.034402] address the question of the origin of the subdiffusional dynamics observed in molecular dynamics (MD) simulations of proteins. Confirming the conclusions of previous publications that used closely similar methods [Neusius et al. Phys. Rev. Lett. 100, 188103 (2008)10.1103/PhysRevLett.100.188103; Phys. Rev. E 83, 021902 (2011)10.1103/PhysRevE.83.021902], Maggi and Orozco conclude that a random walk on a fractal surface is an appropriate model. However, the logic used in their paper to make that conclusion is erroneous.
