5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase is involved in quorum sensing, recycling 5'-methylthioadenosine from the polyamine pathway via adenine phosphoribosyltransferase and recycling 5-methylthioribose to methionine |
| 3.2.2.9 | more |
MTAN is dual-substrate specific and is responsible for the hydrolysis of 5'-methylthioadenosine and S-adenosylhomocysteine to adenine and their corresponding thioriboses |

| 3.2.2.9 | S-adenosyl-L-homocysteine + H2O |
rate of 5'-methylthioadenosine hydrolysis taken as 100%, relative activity 35% |
| 3.2.2.9 | S-adenosyl-L-homocysteine + H2O |
isozyme AtMTAN2 shows markedly broad substrate specificity for hydrolysis of S-adenosyl-L-homocysteine, while isozyme AtMTAN1 does not |
| 3.2.2.9 | S-adenosyl-L-homocysteine + H2O |
substrate of isozyme AtMTAN2, isozyme AtMTAN1 can bind but not hydrolyze S-adenosyl-L-homocysteine |
