 264-358 1.37e-62

Genethonin-1, C-terminal CBM20 (carbohydrate-binding module, family 20) domain. Genethonin-1 is a human skeletal muscle protein with no known function. It contains a C-terminal CBM20 domain. 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.

 264-345 2.86e-10

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.

Disproportionating enzyme 2 (DPE2), N-terminal CBM20 (carbohydrate-binding module, family 20) ...
 279-342 9.25e-10

Disproportionating enzyme 2 (DPE2), N-terminal CBM20 (carbohydrate-binding module, family 20) domain, repeat 2. DPE2 is a transglucosidase that is essential for the cytosolic metabolism of maltose in plant leaves at night. Maltose is an intermediate on the pathway from starch to sucrose and DPE2 is thought to metabolize the maltose that is exported from the chloroplast. DPE2 has two N-terminal CBM20 domains as well as a C-terminal amylomaltase (4-alpha-glucanotransferase) catalytic domain. DPE1, the plastid version of this enzyme, has a transglucosidase domain that is similar to that of DPE2 but lacks the N-terminal CBM20 domains. Included in this group are PDE2-like proteins from Dictyostelium, Entamoeba, and Bacteroides. 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.

 264-355 4.12e-08

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.

 263-345 6.39e-06

CGTase, C-terminal CBM20 (carbohydrate-binding module, family 20) domain. CGTase, also known as cyclodextrin glycosyltransferase and cyclodextrin glucanotransferase, catalyzes the formation of various cyclodextrins (alpha-1,4-glucans) from starch. CGTase has, in addition to its C-terminal CBM20 domain, an N-terminal catalytic domain belonging to glycosyl hydrolase family 13 and an IPT domain of unknown function. 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.

 262-339 4.97e-05

Novamyl (also known as acarviose transferase, ATase, maltogenic alpha-amylase, glucan 1,4-alpha-maltohydrolase, and AcbD), C-terminal CBM20 (carbohydrate-binding module, family 20) domain. Novamyl has a five-domain structure similar to that of cyclodextrin glucanotransferase (CGTase). Novamyl has a substrate-binding surface with an open groove which can accommodate both cyclodextrins and linear substrates. 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.

 264-341 1.48e-03

Beta-amylase, C-terminal CBM20 (carbohydrate-binding module, family 20) domain. Beta-amylase has, in addition to its C-terminal CBM20 domain, an N-terminal catalytic domain belonging to glycosyl hydrolase family 14, which hydrolyzes the alpha-1,4-glucosidic bonds of starch, yielding beta-maltose from the nonreducing end of the substrate. Beta-amylase is found in both plants and microorganisms, however the plant members lack a C-terminal CBM20 domain and are not included in this group. 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.

Prei4, N-terminal CBM20 (carbohydrate-binding module, family 20) domain. Preimplantation protein 4 (Prei4) is a protein of unknown function that is expressed during mouse preimplantation embryogenesis. In addition to the N-terminal CBM20 domain, Prei4 contains a C-terminal glycerophosphoryl diester phosphodiesterase (GDPD) domain. 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.
