Colloquium

Redox-driven proton pumps and biological energy generation

Dr. Alexei  Stuchebrukhov

by: Dr. Alexei Stuchebrukhov

Affiliation: Professor at University of California at Davis

Date: Tuesday May 02, 2017

Time: 2:30 pm – 3:30 pm

Location: Houston Science Center – Building 593 — Room 102

Overview

He will discuss coupled transport of electrons and protons in key enzymes of the electron transport chain of aerobic cells. Electron transport in these enzymes occurs via quantum-mechanical tunneling. Electron tunneling is coupled to proton pumping across the bio-membranes. The resulting proton gradient drives the synthesis of ATP. Computer simulations and theoretical modeling of ET/PT reactions provide important insights into the molecular mechanisms of redox-driven proton pumps and reveals the nature of biological energy generation machinery in aerobic cells.
