FeMoco (FeMo cofactor) is the primary cofactor of nitrogenase. Nitrogenase is the enzyme that catalyzes the conversion of atmospheric nitrogen molecules N 2 into ammonia (NH 3 ) through the process known as nitrogen fixation .
The biosynthesis of the FeMoco active site is highly complex. [13] Structure of the FeMoco active site of nitrogenase. The molybdenum cofactor (pictured) is composed of a molybdenum-free organic complex called molybdopterin, which has bound an oxidized molybdenum(VI) atom through adjacent sulfur (or occasionally selenium) atoms. Except for the ...

Serena DeBeer and her group study this remarkable system comprising a FeMo cofactor (FeMoco) as its active site, and structural model complexes utilizing high-resolution X-ray absorption (XAS) and X-ray emission spectroscopy (XES). Through this work, great progress has been made in understanding the structure of this active site.
