Reaction: S-methyl-5'-thioadenosine + H2O = S-methyl-5'-thioinosine + NH3
Other name(s): MTA deaminase; 5-methylthioadenosine deaminase
Systematic name: S-methyl-5'-thioadenosine amidohydrolase
Comments: The enzyme from Thermotoga maritima also functions as S-adenosylhomocysteine deaminase (EC 3.5.4.28) and has some activity against adenosine. Adenosine 5'-monophosphate and S-adenosyl-L-methionine (SAM) are not substrates.
