Understanding the Electronic Structure Basis for N2 Binding to FeMoco: A Systematic Quantum Mechanics/Molecular Mechanics Investigation
Y Pang, R Bjornsson - Inorganic Chemistry, 2023 - ACS Publications
The FeMo cofactor (FeMoco) of Mo nitrogenase is responsible for reducing dinitrogen to
ammonia, but it requires the addition of 3–4 e–/H+ pairs before N2 even binds. A binding …
