Glucanohydrolase, glucan

Alpha-amylases (1,4-alpha-D-glucan glucanohydrolase, EC 3.2.1.1) have conventionally been employed in starch liquefaction. Alpha-amylases hydrolyze the alpha-1,4-glucosidic linkages of the starch, producing maltodextrins. The alpha-amylases... 

This enzyme [EC 3.2.1.11], also known as o -l,6-glucan-6-glucanohydrolase, catalyzes the endohydrolysis of 1,6-ce-D-glucosidic linkages in dextran.

The in vitro synthesis of cellulose via a nonbiosynthetic path has been achieved for the first time by condensation of [3-D-cellobiosyl fluoride as substrate for cellulase (systematic name 4-[3-D-glucan 4-glucanohydrolase EC 3.2.1.4) in a mixed solvent of acetonitrile/acetate buffer by Kobayashi et al. (see Figure 9.13) [218, 246-249],... 

Pilnik al (7) have noted that the combined action of pecti-nases and C-1 (1,4-p-D-glucan cellobiohydrolase, E.C. 3.2.1.91) enriched cellulases are able to almost completely liquefy pulped fruits and vegetables. For the actual dissolution of the cristal-line cellulose fibrils the C-1 enzyme is necessary which splits off cellobiose from the non-reducing end of the 1,4-p-D-glucan and which needs some C-x (1,4-p-D-glucan-glucanohydrolase, E.C. 3.2.1.4) to create such points of attack. Preparations rich in C-1 activity are usually obtained from Trichoderma spp. (8).
