FIG. 1.

Multiple alignment of sequences of known and putative haloalkane dehalogenases. The sequence designations are explained in Table 1. Secondary elements deduced from the experimentally determined structures of LinB (20), DhaA (24), and DhlA (36) dehalogenases are indicated under the sequences. Catalytic residues are indicated by triangles above the sequences. Active-site residues are enclosed in boxes. Conserved residues (i.e., identical amino acid residues in more than 50% of the sequences) are shaded.
