412056 AA13_LPMO-like 7.61e-160 18 249 1 232
AA13 lytic polysaccharide monooxygenase, and similar proteins. This family contains starch-degrading (also called starch-active) lytic polysaccharide monooxygenase (LPMO), a representative of the new CAZy AA13 family and classified as an auxiliary activity enzyme. This enzyme acts on alpha-linked glycosidic bonds and displays a binding surface that is quite different from those of LPMOs acting on beta-linked glycosidic bonds, indicating that the AA13 family proteins interact with their substrate in a distinct fashion. The active site contains an amino-terminal histidine-ligated mononuclear copper. This enzyme generates aldonic acid-terminated malto-oligosaccharides from retrograded starch and significantly boosts the conversion of this recalcitrant substrate to maltose by beta-amylase.
99886 CBM20_glucoamylase 2.56e-57 287 388 6 106
Glucoamylase (glucan1,4-alpha-glucosidase), C-terminal CBM20 (carbohydrate-binding module, family 20) domain. Glucoamylases are inverting, exo-acting starch hydrolases that hydrolyze starch and related polysaccharides by releasing the nonreducing end glucose. They are mainly active on alpha-1,4-glycosidic bonds but also have some activity towards 1,6-glycosidic bonds occurring in natural oligosaccharides. The ability of glucoamylases to cleave 1-6-glycosidic binds is called "debranching activity" and is of importance in industrial applications, where complete degradation of starch to glucose is needed. Most glucoamylases are multidomain proteins containing an N-terminal catalytic domain, a C-terminal CBM20 domain, and a highly O-glycosylated linker region that connects the two. The CBM20 domain is found in a large number of starch degrading enzymes including alpha-amylase, beta-amylase, glucoamylase, and CGTase (cyclodextrin glucanotransferase). CBM20 is also present in proteins that have a regulatory role in starch metabolism in plants (e.g. alpha-amylase) or glycogen metabolism in mammals (e.g. laforin). CBM20 folds as an antiparallel beta-barrel structure with two starch binding sites. These two sites are thought to differ functionally with site 1 acting as the initial starch recognition site and site 2 involved in the specific recognition of appropriate regions of starch.

99883 CBM20_alpha_amylase 1.58e-37 290 389 3 95
Alpha-amylase, C-terminal CBM20 (carbohydrate-binding module, family 20) domain. This domain is found in several bacterial and fungal alpha-amylases including the maltopentaose-forming amylases (G5-amylases). Most alpha-amylases have, in addition to the C-terminal CBM20 domain, an N-terminal catalytic domain belonging to glycosyl hydrolase family 13, which hydrolyzes internal alpha-1,4-glucosidic bonds in starch and related saccharides, yielding maltotriose and maltose. Two types of soluble substrates are used by alpha-amylases including long substrates (e.g. amylose) and short substrates (e.g. maltodextrins or maltooligosaccharides). The CBM20 domain is found in a large number of starch degrading enzymes including alpha-amylase, beta-amylase, glucoamylase, and CGTase (cyclodextrin glucanotransferase). CBM20 is also present in proteins that have a regulatory role in starch metabolism in plants (e.g. alpha-amylase) or glycogen metabolism in mammals (e.g. laforin). CBM20 folds as an antiparallel beta-barrel structure with two starch binding sites. These two sites are thought to differ functionally with site 1 acting as the initial starch recognition site and site 2 involved in the specific recognition of appropriate regions of starch.
