IUBMB Enzyme Nomenclature

EC 3.5.4.31

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 3.5.4.28) and has some activity against adenosine. Adenosine 5'-monophosphate and S-adenosyl-L-methionine (SAM) are not substrates.
