Protein: 5-methylthioadenosine/S-adenosylhomocysteine deaminase (MTA/SAH deaminase) (EC 3.5.4.28) (EC 3.5.4.31) (Q9X034)
Organism: Thermotoga maritima (strain ATCC 43589 / DSM 3109 / JCM 10099 / NBRC 100826 / MSB8)
Function: Catalyzes the deamination of 5-methylthioadenosine and S-adenosyl-L-homocysteine into 5-methylthioinosine and S-inosyl-L-homocysteine, respectively. Is also able to deaminate adenosine. Adenosine-5-monophosphate (AMP) and S-adenosyl-L-methionine (SAM) are not enzyme substrates.
