    All mononuclear molybdoenzymes bind molybdenum in a complex with an organic cofactor termed molybdopterin (MPT). In many bacteria, including Escherichia coli, molybdopterin can be further modified by attachment of a GMP group to the terminal phosphate of molybdopterin to form molybdopterin guanine dinucleotide (MGD). This modification reaction is required for the functioning of many bacterial molybdoenzymes, including the nitrate reductases, dimethylsulfoxide (DMSO) and trimethylamine-N-oxide (TMAO) reductases, and formate dehydrogenases. The GMP attachment step is catalyzed by the cellular enzyme MobA.
