The beta-galactosidase gene of Streptococcus pneumoniae, bgaA, encodes a putative 2,235-amino-acid protein with the two amino acid motifs characteristic of the glycosyl hydrolase family of proteins. In addition, an N-terminal signal sequence and a C-terminal LPXTG motif typical of surface-associated proteins of gram-positive bacteria are present. Trypsin treatment of cells resulted in solubilization of the enzyme, documenting that it is associated with the cell envelope. In order to obtain… CONTINUE READING
