FIGURE 1.

Amino acid sequences of BmSUC1 and BmSUC2. Amino acid sequences were compared with the sequence of β-fructofuranosidase from the bacterium B. licheniformis ATCC 14580 (GenBank™ accession number AAU25612). Sequences were aligned with the ClustalX program (19). Using the Boxshade program, identical and similar residues, in more than two sequences, have been highlighted in black and gray, respectively. Putative signal peptides are boxed, and the active sites of the yeast invertase (23) are underlined.
