A Quantum Mechanical Aspect of Enzyme Action: Enzymes as Information Driven Quantal Measurement Engines

In this introductory paper we overview existing approaches to enzyme – catalysed reactions. From the Michaelis – Menten kinetics to quantum scatterings several models are considered. We try to introduce our ”information – driven measurement engines” (an other model of enzyme action) in relation to existent theories. We conclude that our approach is a special type of quantum mechanical treatment of enzyme catalysed reactions, in its nascent form. It is, we suppose, stands more in relation to a hypothetical gas – phase scattering, maybe even resonance scattering, as a one – dimensional vacuum energy – dependent motion along the reaction path. We are aware that at this time, no realistic gas – phase scattering is available in the area, and our approach is thus similarly hypothetical. Still, it might provide a fresh view on enzyme – catalysed reactions, utilising a somewhat unusual Hamiltonian second – order tensor operator formalism. During arriving at our goal, we give some more extensive review devoted to current catalyzed and uncatalized reaction investigations, of a pure chemical and biochemical nature, exploring both experimental and theoretical procedures.
