Accepted name: S-methyl-5′-thioadenosine deaminase
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 and has some activity against adenosine. Adenosine 5′-phosphate and S-adenosyl-L-methionine (SAM) are not substrates.
