FIG. 2.

Alignment of the deduced amino acid sequence of sulfoglycosidase from Prevotella strain RS2 with homologous sequences. Prevotella RS2, sulfoglycosidase from Prevotella strain RS2; B. thetaiotaomicron, β-hexosaminidase precursor from B. thetaiotaomicron; Homo sapiens, β-N-acetylhexosaminidase subunit A from H. sapiens. Alignment was carried out by using Clustal W (1.82) multiple-sequence alignment. Fully conserved residues (asterisks) and residues with one conservative replacement (colons) are highlighted.
