first introduction of H at the NFe7MoS9(homocitrate) active site is via a water chain terminating at water 679 to S3B of the my3-S atoms of the active site. Discussion of subsequent movement of the H atoms around the NFe7MoS9(homocitrate) preparatory to the binding and hydrogenation of N2 and other substrates. S2B has a modulatory function and is not an H-entry site |
