Exo-inulinase of Aspergillus niger N 402 : A hydrolytic enzyme with significant transfructosylating activity

The purified exo-inulinase enzyme ofAspergillus nigerN402 (AngInuE; heterologously expressed in Escherichia coli) displayed a sucrose:inulin (S/I) hydrolysis ratio of 2.3, characteristic for a typical exo-inulinase. The enzyme also had significant transfructosylating activity with increasing sucrose concentrations, producing various oligosaccharides. The… CONTINUE READING
