Figure 3

Alignment of the amino acids sequences of β- D -galactosidase (A) acid-base active sites, and (B) the consensus nucleophilic region of the selected LacZ enzymes and Paracoccus sp. 32d β- D -galactosidase The numbers in parentheses are GenBank accession numbers. Proposed active site glutamic acid residues are indicated by the black arrows.
