Abstract

Proton NMR spectroscopy and HPLC have been used to investigate the hydrolysis of cellooligosaccharides and cellulose by cellobiohydrolase II from Trichoderma reesei. The cleavage pattern for the substrates cellotriose to cellohexaose has been determined. The catalytic rates were higher for the natural substrates (3.6-300 min-1) than the rates earlier reported for chromophoric cellooligosaccharide derivatives (0.821 min-1). The cellulose hydrolysis is slow compared to the hydrolysis of the soluble cellooligosaccharides. The cellotriose hydrolysis is inhibited by glucose and the inhibition is non-competitive. Cellobiohydrolase II retains maximal activity in a broad pH range, 2.5-6.5.
