Pullulanase
Definition:
EC Tree > 3 Hydrolases > 3.2 Glycosylases > 3.2.1 Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds > 3.2.1.41 pullulanase
Pullulanase is a debranching amylase that hydrolyses (1->6)-alpha-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the alpha- and beta-limit dextrins of amylopectin and glycogen; it differs from limit dextrinase (EC 3.2.1.142) in its action on glycogen and its rate on limit dextrins, its action on amylopectin is complete, and maltose is the smallest sugar it can release from an alpha-(1->6)-linkage. By debranching starch it increases fermentable sugar yield in starch processing and brewing. It is distributed across Bacteria, Eukaryota and Archaea.
