    • 15h that a new microscopic model (called AVB) had been developed. This argument was based on the assertion that the EVB model is calibrated on macroscopic thermodynamic data while the so-called AVB approach is calibrated on ab initio gas-phase results. This argument reflects a very problematic perspective. First, the EVB model provides fully microscopic all-atom molecular surfaces that are always calibrated on the most reliable information available at the given time. This, of course, includes ab initio results when these results are considered to be sufficiently reliable (e.g., refs. 14d, 15d, and 15i). Second, the argument that calibration of a microscopic model using macroscopic properties makes the model macroscopic is simply misleading. As is now obvious to almost all workers in the field one of the best ways of calibrating microscopic models is the use of these models in simulations of average properties (e.g., solvation free energies) and then using the agreement between the calculated and observed properties in refining the microscopic level. This is, for example, the approach used in refining popular water models and many force fields. Finally, as a note of caution, even now, with very powerful ab initio approaches, it is important to verify the calculated results using experimental information about the given reaction in solution. This is demonstrated in the present work and not doing so will lead to incorrect results in calculations of complex systems such as enzymatic reactions.
