The passage around this formula
The best-established non-trivial quantum effect in biology generates none of the excitement the other three cases have attracted, largely because it never needed a correction: enzymatic hydrogen transfer has been recognized as a quantum-tunneling phenomenon, not a classical over-the-barrier reaction, since kinetic isotope effect measurements in the 1980s and 1990s began returning numbers no classical transition-state theory could accommodate. A classical reaction’s kinetic isotope effect — the rate ratio between a protium-substituted and a deuterium-substituted substrate — is bounded by the difference in zero-point vibrational energy between the two isotopes, which caps the semiclassical…
