Glycerophosphodiester phosphodiesterase domain of putative mammalian glycerophosphodiester phosphodiesterase GDE5 and similar proteins; This subfamily corresponds to the glycerophosphodiester phosphodiesterase domain (GDPD) present in putative mammalian GDE5 and similar proteins. Mammalian GDE5 is widely expressed in mammalian tissues, with highest expression in the spinal chord. Although its biological function remains unclear, mammalian GDE5 shows higher sequence homology to fungal and plant glycerophosphodiester phosphodiesterases (GP-GDEs, EC 3.1.4.46) than to other bacterial and mammalian GP-GDEs. It may also hydrolyze glycerophosphodiesters to sn-glycerol-3-phosphate (G3P) and the corresponding alcohols. In addition to C-terminal GDPD domain, all members in this subfamily have a starch binding domain (CBM20) in the N-terminus, which suggests these proteins may play a distinct role in glycerol metabolism. : Pssm-ID: 176549 [Multi-domain] Cd Length: 290 Bit Score: 430.56 E-value: 1.12e-147

The family 20 carbohydrate-binding module (CBM20), also known as the starch-binding 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.

Glycerophosphodiester phosphodiesterase domain as found in prokaryota and eukaryota, and similar proteins; The typical glycerophosphodiester phosphodiesterase domain (GDPD) consists of a TIM barrel and a small insertion domain named the GDPD-insertion (GDPD-I) domain, which is specific for GDPD proteins. This family corresponds to both typical GDPD domain and GDPD-like domain which lacks the GDPD-I region. Members in this family mainly consist of a large family of prokaryotic and eukaryotic glycerophosphodiester phosphodiesterases (GP-GDEs, EC 3.1.4.46), and a number of uncharacterized homologs. Sphingomyelinases D (SMases D) (sphingomyelin phosphodiesterase D, EC 3.1.4.41) from spider venom, SMases D-like proteins, and phospholipase D (PLD) from several pathogenic bacteria are also included in this family. GDPD plays an essential role in glycerol metabolism and catalyzes the hydrolysis of glycerophosphodiesters to sn-glycerol-3-phosphate (G3P) and the corresponding alcohols are major sources of carbon and phosphate. Its catalytic mechanism is based on the metal ion-dependent acid-base reaction, which is similar to that of phosphoinositide-specific phospholipases C (PI-PLCs, EC 3.1.4.11). Both, GDPD related proteins and PI-PLCs, belong to the superfamily of PI-PLC-like phosphodiesterases. Pssm-ID: 176499 [Multi-domain] Cd Length: 189 Bit Score: 99.26 E-value: 7.09e-24

GDE1 is widely expressed in mammalian tissues, including the heart, brain, liver, and kidney. It shows sequence homology to bacterial glycerophosphodiester phosphodiesterases (GP-GDEs, EC 3.1.4.46), which catalyzes the hydrolysis of various glycerophosphodiesters, and produce sn-glycerol-3-phosphate (G3P) and the corresponding alcohols. GDE1 has been characterized as GPI-GDE (EC 3.1.4.44) that selectively hydrolyzes extracellular glycerophosphoinositol (GPI) to generate glycerol phosphate and inositol. It functions as an integral membrane-bound glycoprotein interacting with regulator of G protein signaling protein RGS16, and is modulated by G protein-coupled receptor (GPCR) signaling. In addition, GDE1 may interact with PRA1 domain family, member 2 (PRAF2, also known as JM4), which is an interacting protein of the G protein-coupled chemokine receptor CCR5. The catalytic activity, which is dependent on the integrity of the GDPD domain, is required for GDE1 cellular function.

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).

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.
