Other name(s): 5′-methylthioadenosine nucleosidase; MTA nucleosidase; MeSAdo nucleosidase; methylthioadenosine methylthioribohydrolase; MTN1 (gene name)
Systematic name: S-methyl-5′-thioadenosine adeninehyrolase
Comments: Unlike EC, adenosylhomocysteine nucleosidase, this plant enzyme has little or no activity with S-adenosyl-L-homocysteine.
