Using classical molecular-dynamics simulations based on the OPLS-AA force field we study the adsorption of a BMP-2 molecule to a hydrophobic graphite surface. Using an implicit inviscid water model, the adsorption dynamics and energetics are monitored for four different initial protein orientations towards the surface. In all cases we find that the protein partially unfolds and spreads on the surface. We conclude that due to the substantially denatured protein structure, interactions of the adsorbed BMP-2 with cell receptors might be unlikely.
