TABLE 2.

Sequence identities of atzABC homologs from different atrazine-degrading bacteria

Strain	% DNA sequence identitya
	atzA	atzB	atzC
Pseudomonas ADP	100	100	100
Alcaligenes SG1	99.2	100	100
Ralstonia M91-3	99.0	100	100
Agrobacterium J14a	99.1	100	100
Isolate 38/38	99.3	100	99.8

^aDNA sequences obtained from each strain by using the ataA, -B, and -C primers were compared with the atzABC gene sequences from Pseudomonas strain ADP.
