EC 3.5.1.131 Details
EC number
3.5.1.131
Accepted name
1-carboxybiuret hydrolase
Reaction
1-carboxybiuret + H2O = urea-1,3-dicarboxylate + NH3
Other name(s)
atzEG (gene names)
Systematic name
1-carboxybiuret amidohydrolase
Comment
The enzyme, characterized from the bacterium Pseudomonas sp. ADP, participates in the degradation of cyanuric acid, an intermediate in the degradation of s-triazine herbicides such as atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine]. The enzyme is a heterotetramer composed of a catalytic subunit (AtzE) and an accessory subunit (AtzG) that stabilizes the complex.
