3.2.1.B26 additional information the enzyme shows broad specificity for beta-D-gluco-, fuco- and galactosides. It hydrolyses a large number of beta-linked glycoside dimers and oligomers; chromogenic beta-glucosides and beta-fucosides are the preferred substrates, and kinetic analysis indicates that they bind to a common catalytic site. The order of catalytic efficiency is beta 1-3 > beta 1-4 > beta 1-6 and cellotetraose > cellotriose > cellobiose for glucose dimers and oliogomers respectively. The cleavage occurres at the non-reducing end of the oligosaccharide, and the enzyme shows noticeable specificity also for the aglycone part of substrates. The enzyme from Sulfolobus solfataricus strain MT-4 is defined as a true glycosyl hydrolase with remarkable exo-glucosidase activity Saccharolobus solfataricus ?
