Wackett Department of Biochemistry, Molecular Biology and Biophysics and Biotechnology Institute, 1479 Gortner Avenue, University of Minnesota, St. Paul, M N 55108 Pseudomonas sp. ADP was used as a model to investigate how bacteria evolve new enzymes in new combinations to metabolize s-triazine herbicides. The metabolic pathway provides inorganic nitrogen to support microbial growth. The enzymes that initiate the metabolism of the herbicide atrazine are denoted AtzA, AtzB and AtzC.

The CBDOPH and ELP-OPH fusion system offers an attractive one-step purification and immobilization of enzymes. The advent of DNA shuffling and directed evolution strategies has opened up an entire new realm in protein engineering where an enzyme can be "tuned" to target a wide array of substrates. Although the use of these technologies in large-scale operations is limited to date, we will eventually turn to these methods as the technology matures and as the public starts to demand the use of more environmentallyfriendlytreatment methods.

The phase transition is a hydrophobically driven process causing the side chains of hydrophobic amino acid residues aggregating to a thermodynamically favorable state with the increase in temperature or ionic strength (27). This thermally triggered property of phase transition allowed for a simple and rapid means of purifying die fusion protein. Over 1300-fold purification was achieved after only 2 cycles of inverse phase transition. The purified fusion protein showed essentially identical kinetic properties as native ΟΡΗ with only a 10% increase in K and a 5% increase of Kca .
