The enzymes discriminate the substrate probably by recognizing the sulfation pattern of the digalactose reapeting unit of the polysaccharide. lambda-Carrageenas present conserved arginine residues in the catalytic site which are believed to interact with carrageenans in which both sugar residues in the disaccharide units are negatively charged Bacillus sp.
