IUBMB Enzyme Nomenclature


Accepted name: hydroxydechloroatrazine ethylaminohydrolase

Reaction: 4-(ethylamino)-2-hydroxy-6-(isopropylamino)-1,3,5-triazine + H2O = N-isopropylammelide + ethylamine

Other name(s): AtzB; hydroxyatrazine ethylaminohydrolase

Systematic name: 4-(ethylamino)-2-hydroxy-6-(isopropylamino)-1,3,5-triazine ethylaminohydrolase

Comments: Involved in a pathway by which the herbicide atrazine, 2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5-triazine, is degraded in bacteria via N-isopropylammelide, 2,4-dihydroxy-6-(isopropylamino)-1,3,5-triazine.
