Microbial formate dehydrogenases (FDH) are molybdenum-containing enzymes that can catalyse the reduction of CO2 into formate. Here, the authors suggest a structural and functional basis for sulphuration of the molybdenum cofactor in E. coliFDH, a key step in the production of active formate dehydrogenase.
