RC STRAIN=MS {ECO:0000313|EMBL:AKB55085.1}; RA Henriksen J.R., Luke J., Reinhart S., Benedict M.N., Youngblut N.D., RA Metcalf M.E., Whitaker R.J., Metcalf W.W.; RT "Methanogenic archaea and the global carbon cycle."; RL Submitted (JUL-2014) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the deamination of 5'-deoxyadenosine into 5'- CC deoxyinosine. May be involved in the recycling of 5'- CC deoxyadenosine, whereupon the 5'-deoxyribose moiety of 5'- CC deoxyinosine is further metabolized to deoxyhexoses used for the CC biosynthesis of aromatic amino acids in methanogens. Is also able CC to deaminate 5-methylthioadenosine, S-adenosyl-L-homocysteine and CC adenosine to a small extent. {ECO:0000256|HAMAP-Rule:MF_01281}. CC -!- CATALYTIC ACTIVITY: 5'-deoxyadenosine + H(2)O = 5'-deoxyinosine + CC NH(3). {ECO:0000256|HAMAP-Rule:MF_01281}. CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000256|HAMAP- CC Rule:MF_01281}; CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01281}; CC -!- SIMILARITY: Belongs to the MTA/SAH deaminase family.
