3.5.4.45 |
Accepted name: |
melamine deaminase |
Reaction: |
(1) melamine + H2O = ammeline + NH3 (2) ammeline + H2O = ammelide + NH3 |
Glossary: |
melamine = 2,4,6-triamino-1,3,5-triazine
ammeline = 4,6-diamino-1,3,5-triazin-2-ol
ammelide = 6-amino-1,3,5-triazine-2,4-diol |
Other name(s): |
triA (gene name) |
Systematic name: |
melamine aminohydrolase |
Comments: |
The enzyme, isolated from the bacterium Acidovorax citrulli, performs the deamination of melamine 15-fold faster than the deamination of ammeline. It also has activity with 2-chloro-4,6-diamino-s-triazine, but has no activity toward halo-substituted triazine ring compounds such as atrazine (cf. EC 3.8.1.8, atrazine chlorohydrolase). |
