Metabolite ID PAMDB120060
Identification Name:
ribose-1-arsenate Description: Ribose-1-arsenate is an intermediate in arsenate detoxification I pathway. Arsenic detoxification in most mammals involves alternative steps of reduction and oxidative methylation. The end metabolites are methylarsonate,cacodylate, and dimethylarsinous acid,which are less reactive than arsenate and arsenite, and are excreted in the urine.The pathway starts with the reduction of arsenate to arsenite. In this process,arsenate can be conjugate to ribose by the enzyme purine nucleoside phosphorylase (PNP), which accepts arsenate as an alternative substrate to its normal substrate, phosphate. The ribose-1-arsenate thus formed is converted to arsenite in the presence of dihydrolipoate, in a process that has not been fully characterized yet.
