Proton transfer is the commonest reaction that enzymes perform. Most enzyme reactions go by ionic mechanisms, involving the creation or disappearance of charge. Such reactions are typically acid- or base-catalysed, but acid and base concentrations are minimal under physiological conditions near pH 7....
