In enzymology, a methylthioadenosine nucleosidase (EC 3.2.2.16) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are S-methyl-5'-thioadenosine and H2O, whereas its two products are S-methyl-5-thio-D-ribose and adenine.
This enzyme belongs to the family of hydrolases, specifically those glycosylases that hydrolyse N-glycosyl compounds.
The systematic name of this enzyme class is S-methyl-5'-thioadenosine adeninehyrolase.
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1NC1, 1NC3, 1Y6Q, 1Y6R, 1ZOS, and 2H8G.
