Isolated and purified DNA molecule and protein for the degradation of triazine compounds

An isolated and purified DNA molecule encoding atrazine chlorohydrolase;

• the DNA molecule hybridizes to DNA complementary to DNA having the sequence shown in FIG. 6 (SEQ ID NO:1), beginning at position 236 and ending at position 1655, under the stringency conditions of hybridization in buffer containing 0.25 M Na2HPO4, 7% SDS, 1% BSA, 1.0 mM EDTA at 65° C., followed by washing with 0.1% SDS and 0.1×SSC at 65° C.
