Identification
Name: Cyclic pyranopterin monophosphate
Description:Cyclic pyranopterin monophosphate is a member of the chemical class known as Pterins and Derivatives. These are polycyclic aromatic compounds containing a pterin moeity, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. cPMP is a precursor to molybdenum cofactor, which is required for the enyzme activity of sulfite oxidase, xanthine dehydrogenase/oxidase and aldehyde oxidase. The transition element molybdenum (Mo) has been long known as an essential micronutrient across the kingdoms of plants, animals, fungi and bacteria. However, molybdate itself is catalytically inactive and, with the exception of bacterial nitrogenase, needs to be activated through complexation by a special cofactor. There are several molybdenum cofactors, including molybdopterin (MPT), guanylyl molybdenum cofactor (MGD), cytidylyl molybdenum cofactor, or others. In Pseudomonas aeruginosa, the MoaD protein plays a central role in the conversion of precursor Z to molybdopterin (MPT) during molybdenum cofactor biosynthesis. (PMID 17223713) In Pseudomonas aeruginosa, MPT is formed by incorporation of two sulfur atoms into precursor Z, which is catalyzed by MPT synthase. (PMID 11459846)
