EC 3.5.1.84

Names

Accepted name:
biuret amidohydrolase
Systematic name:
biuret amidohydrolase

Reaction

Comments:

The enzyme, characterized from the bacterium Rhizobium leguminosarum bv. viciae 3841, participates in the degradation of cyanurate, an intermediate in the degradation of s-triazide herbicides such as atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine]. The substrate, biuret, forms by the spontaneous decarboxylation of 1-carboxybiuret in the absence of 1-carboxybiuret hydrolase.
