Metabolite Identification
Common NameAdenylyl-molybdopterin
DescriptionAdenylyl-molybdopterin, also known as mpt-amp, belongs to the class of organic compounds known as molybdopterin dinucleotides. These are a dinucleotide that is made up of a molybdopterin and a purine or pyrimidine base linked to each other through a phosphate chain. Adenylyl-molybdopterin is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Outside of the human body, adenylyl-molybdopterin can be found in a number of food items such as teff, tamarind, prairie turnip, and summer savory. This makes adenylyl-molybdopterin a potential biomarker for the consumption of these food products.

General function:
Involved in Mo-molybdopterin cofactor biosynthetic process
Specific function:
Microtubule-associated protein involved in membrane protein-cytoskeleton interactions. It is thought to anchor the inhibitory glycine receptor (GLYR) to subsynaptic microtubules (By similarity). Catalyzes two steps in the biosynthesis of the molybdenum cofactor. In the first step, molybdopterin is adenylated. Subsequently, molybdate is inserted into adenylated molybdopterin and AMP is released.
