FIG. 1.

Alignment of amino acid sequences of PGPases from several organisms. The amino acid sequences of E. coli (p32662), K. aerogenes (Q9EYY5), H. influenzae (p44755), R. eutropha (p40852), and A. tumefaciens (AAL42616) are shown. Asterisks indicate residues that were conserved in at least four of the aligned sequences. Shaded residues correspond to the putative catalytic domain for phosphatase activity described by Galinier et al. (9). Alignments of the amino acid sequences were generated by using the PILEUP program of the Genetics Computer Group software package (University of Wisconsin).
