Molybdopterins

Cofactors or analogs thereof, with a structure based on a furan ring fused to a pterin. In addition, the pyran ring features two thiolates, which serve as ligands in molybdo- and tungstoenzymes. In some cases, the alkyl phosphate group is replaced by an alkyl diphosphate nucleotide.
