P23658 · GUNC_BUTFI

Function

function

Glycoside hydrolase that rapidly hydrolyzes short-chain cellodextrins to yield either cellobiose or cellobiose and glucose as end products; cellobiose is not hydrolyzed further. Also shows limited activity against endoglucanase specific substrates (carboxymethylcellulose (CMC), lichenan, laminarin and xylan).

Catalytic activity

  • Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
    EC:3.2.1.4 (UniProtKB | ENZYME | Rhea)

Activity regulation

Is not inhibited by methylcellulose.
