Enzyme Information
| 3.2.2.9 |
Adenosylhomocysteine nucleosidase.
based on mapping to UniProt Q9ZMY2
S-adenosyl-L-homocysteine + H(2)O = S-(5-deoxy-D-ribos-5-yl)-L- homocysteine + adenine.
|
| 3.2.2.30 |
Aminodeoxyfutalosine nucleosidase.
based on mapping to UniProt Q9ZMY2
6-amino-6-deoxyfutalosine + H(2)O = dehypoxanthine futalosine + adenine.
-!- The enzyme, found in several bacterial species, catalyzes a step in a modified futalosine pathway for menaquinone biosynthesis. -!- While the enzyme from some organisms also has the activity of EC 3.2.2.9 the enzyme from Chlamydia trachomatis is specific for 6-amino-6-deoxyfutalosine.
