nitroethane + H2O solvent isotope and viscositiy effects: the kcat proton inventory is consistent with a single exchangeable proton in flight, while the kcat/KM is consistent with either a single proton in flight in the transition state or a medium effect. Increasing the solvent viscosity does not affect the kcat or kcat/KM value significantly, establishing that nitroethane binding is at equilibrium and that product release does not limit kcat Fusarium oxysporum ethanal + nitrite + H2O2
