the proximal hydrogen bond modulation at residue W66 can selectively decrease or increase the electron donating properties of the proximal thiolate. The modulation controls the sigma-competition between distal and proximal ligands and controls the stability of various NOS intermediates. A fine tuning of the electron donation by the proximal ligand is required to allow at the same time oxygen activation and to prevent uncoupling reactions |
