MTA phosphorylase catalyzes the cleavage of adenine from S-methylthioadenosine (MTA) and subsequent phosphorylation of the product, yielding 5'-methylthio ribose-1-phosphate (Kamatani et al. 1981). The active form of the enzyme is a homotrimer (Della Ragione et al. 1985). Mutations in the gene are associated with a rare bone dysplasia and cancer syndrome, DMS-MFH (Camacho-Vanegas et al. 2012).
