Fig. 5

The pairwise sequence alignment results of DehLBHS1 and L-DEX YL from Pseudomonas sp. strain YL (Nardi-Dei et al., 1997). Mark in bold were three key amino acids (D,Asp; R,Arg; S,Ser), which play an important role in the catalytic function of L-DEX YL haloacid dehalogenase. The three key amino acids (in bold) also were located in DehLBHS1 in the same position except for S(Ser). * symbol indicates a stop codon
