Scientists Capture Elusive Sodium Pump in Action, Solving a Long-Standing Biological Mystery

A long-standing mystery in bacterial bioenergetics is beginning to unravel as researchers capture fleeting structural states of a sodium-pumping enzyme in action. The enzyme Na⁺-NQR acts as a sodium pump that fuels respiration in many marine and disease-causing bacteria. It relies on redox reactions, which involve the transfer of electrons between molecules, to move sodium [...]
