Climbing Nitrogenase: Toward a Mechanism of Enzymatic Nitrogen Fixation

DOI: 10.1021/ar8002128 Authors: Brian M. Hoffman, Dennis R. Dean, Lance C. Seefeldt Abstract: « Nitrogen fixation », the reduction of dinitrogen (N2) to two ammonia (NH3) molecules, by the Mo-dependent nitrogenase is essential for all life. Despite four decades of...

A Synthetic Single-Site Fe Nitrogenase: High Turnover, Freeze-Quench ⁵⁷Fe Mössbauer Data, and a Hydride Resting State

DOI: 10.1021/jacs.6b01706 Authors: Trevor J. Del Castillo, Niklas B. Thompson, Jonas C. Peters Abstract: The mechanisms of the few known molecular nitrogen-fixing systems, including nitrogenase enzymes, are of much interest but are not fully understood. We recently...
