ID 3.5.1.131 DE 1-carboxybiuret hydrolase. CA 1-carboxybiuret + H2O = NH4(+) + urea-1,3-dicarboxylate. CC -!- The enzyme, characterized from the bacterium Pseudomonas sp ADP, CC participates in the degradation of cyanuric acid, an intermediate in CC the degradation of s-triazine herbicides such as atrazine [2-chloro- CC 4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine]. CC -!- The enzyme is a heterotetramer composed of a catalytic subunit (AtzE) CC and an accessory subunit (AtzG) that stabilizes the complex. DR Q936X3, ATZE_PSESD ; //
