S-methyl-5'-thioadenosine deaminase (EC 3.5.4.31, MTA deaminase, 5-methylthioadenosine deaminase) is an enzyme with systematic name S-methyl-5'-thioadenosine amidohydrolase.[1] This enzyme catalyses the following chemical reaction

S-methyl-5'-thioadenosine + H2O 5'-S-methyl-5'-thioinosine + NH3

The enzyme from Thermotoga maritima also functions as S-adenosylhomocysteine deaminase (EC 3.5.4.28).
