"ENZYMES can employ a weird quantum trick called tunnelling. Simply put, the enzyme encourages a process whereby electrons and protons vanish from one position in a biochemical and instantly rematerialise in another, without visiting any of the in-between places – a kind of teleportation." https://lnkd.in/eYXPebN View in LinkedIn

ENZYME QUANTUM TUNNELING. "Researchers have known for several years that in some enzyme-catalysed reactions, protons move from one molecule to another by the quantum-mechanical phenomenon of tunnelling, in which a particle passes through an energy barrier rather than having to muster the energy to climb over it." https://lnkd.in/eDJed9B View in LinkedIn

QUANTUM ENZYMES. "Hydrogen tunnelling also plays an important role in a wide range of biological enzymatic catalytic reactions. Observations of strong intrinsic kinetic isotope effects in enzymatic reactions have clearly demonstrated nuclear quantum effects in enzymes." https://lnkd.in/eRUdQZj View in LinkedIn

ADAPTIVE MUTATION. "In 1999, the physicist Jim Al-Khalili and I suggested that proton tunnelling might account for one very peculiar kind of mutation – so-called adaptive mutation – which appears to occur more frequently when it provides an advantage. Our paper was entirely theoretical, but we are currently attempting to find experimental evidence for proton tunnelling in DNA." https://lnkd.in/eYXPebN View in LinkedIn

"BIOLOGICAL PHOTORECEPTORS contain chromophores that absorb photons and then undergo rapid chemical transformation on their excited states, eventually leading to light-induced signal transduction. Owing to the quantum nature of electronically excited states and nuclear quantum coherences that often accompany excited-state molecular dynamics, quantum mechanics is required to describe these photoactivated dynamics in biological photoreceptors." https://lnkd.in/eRUdQZj View in LinkedIn

RHODOPSIN. "The remarkably rapid and efficient photoactivated one-way reaction dynamics in rhodopsin is a result of the ultrafast coherent wave-packet dynamics that depends critically on the quantum mechanical positioning of the excited-state potential energy surfaces and the symmetries of the electronic states." https://lnkd.in/eRUdQZj View in LinkedIn
