ID 3.5.1.84 DE biuret amidohydrolase. CA biuret + H2O = NH4(+) + urea-1-carboxylate. CC -!- The enzyme, characterized from the bacterium Rhizobium leguminosarum CC bv. viciae 3841, participates in the degradation of cyanurate, CC an intermediate in the degradation of s-triazide herbicides such as CC atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine]. CC -!- The substrate, biuret, forms by the spontaneous decarboxylation of CC 1-carboxybiuret in the absence of 1-carboxybiuret hydrolase. DR Q1M7F4, BIUH_RHIJ3 ; //
