    Functioni

    Exo-fructosidase that can hydrolyze both levan and inulin, leading to the production of free fructose. Is also able to hydrolyze sucrose and to a small extent raffinose, but not melezitose, stachylose, cellobiose, maltose, and lactose.1 Publication

    Catalytic activityi

    Hydrolysis of terminal, non-reducing (2->1)- and (2->6)-linked beta-D-fructofuranose residues in fructans.

    Enzyme regulationi

    Is completely inhibited by Ag+ and Hg2+ ions.1 Publication

    Kineticsi

    1. KM=1.2 µM for levan (at pH 5.5 and 55 degrees Celsius)1 Publication
    2. KM=6.7 mM for inulin (at pH 5.5 and 55 degrees Celsius)1 Publication
    3. KM=64 mM for sucrose (at pH 5.5 and 55 degrees Celsius)1 Publication

    pH dependencei

    Optimum pH is 5.5 for inulin hydrolysis.1 Publication

    Temperature dependencei

    Optimum temperature is 55 degrees Celsius for inulin hydrolysis. Is rapidly inactivated at 60 degrees Celsius. High stable at 50 and 55 degrees Celsius.1 Publication
