ENZYME entry: EC 3.5.4.45

Accepted Name
Melamine deaminase.
Reaction catalysed
  • Melamine + H(2)O <=> ammeline + ammonia
  • Ammeline + H(2)O <=> ammelide + ammonia
Cofactor(s)
Fe(2+).
Comment(s)
  • 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).
  • Formerly EC 3.5.4.n3.
