Uptake of iodinated human kidney alpha-D-mannosidase by rat liver- Association with membrane elements and stability in vivo and in vitro. (1/153)

1. Human kidney alpha-D-mannosidase (form A) was labelled with 125I to a specific radio-activity of approx. 2250muCi/mg of protein, essentially without loss of enzymic activity. The enzymic activity and radioactivity of the iodinated material also co-migrated in gel filtration and gel electrophoresis. 2. The binding of 125I-labelled mannosidase in vitro to particulate material in liver and kidney homogenates was of the other of 2 pg/mg of particulate material in liver and kidney homogenates was of the order of 2pg/mg of particulate protein withing 16h at 37 degrees C, and essentially zero in intervals of up to 60 min. The degradation in vitro of labelled exogenous mannosidase was of the order of 10-20pg/ 16th per mg of protein in postnuclear supernatant, and it was saturated entirely within 1h at 37 degrees C. 3. The binding of labelled mannosidase in vivo to particulate elements of liver homogenates 60 min after intravenous injection was at least 10 times higher in terms of specific radioactivity than the highest value attainable in vitro. Virtually all exogenous enzyme bound to liver particulate material could be recovered in macromolecular form after disruption of membranes by detergents. 4. The radioactive enzyme bound to liver particulate material could be detached almost completely by shearing, repeated freezing and thawing, and exposure to strong detergents under conditions that do not eliminate rough-endoplasmic-membrane structure. It could bot be released, however, by high salt concentration (0.5M-KC1) or by exposure to weak detergents such as Tween 80. The particle-bound enzyme should thus be associated with plasma membranes and lysosome-like elements. 5. Of the rat tissues studied, only liver could approach, within 60 min after the injection, the concentration of exogenous mannosidase found in the blood serum. The activity per g tissue weight fell progressively from liver (60% of serum value) to kidney (16% of serum value), lung (8% of serum vlaue), spleen (6% of serum value) and brain (0.9% of serum value). Most of the radioactive enzyme found in tissues other than liver appeared to be present in a free form, whereas in liver more than 50% of the labelled enzyme was associated with membrane elements.  (+info)

The structural gene for alpha-mannosidase-1 in Dictyostellium discoideum. (2/153)

We have isolated 4 independent mutations affecting alpha-mannosidase-1, a developmentally regulated activity in Dictyrostelium discoideum. Three of these result in a thermolabile alpha-mannosidase-1 activity. One mutation also affects the substrate affinity (Km) of the activity. In diploids these mutations show a gene dosage effect and are all alleles. The structural gene for alpha-mannosidase-1, as defined by these mutations, defines a new linkage group, linkage group VI. alpha-mammosidase 1 is probably a homopolymer with subunits of 54,000 daltons. We have also mapped two temperature-sensitive-for-growth mutations onto two previously defined linkage groups.  (+info)

Saccharomyces boulardii upgrades cellular adaptation after proximal enterectomy in rats. (3/153)

BACKGROUND: Saccharomyces boulardii is a non-pathogenic yeast which exerts trophic effects on human and rat small intestinal mucosa. AIMS: To examine the effects of S boulardii on ileal adaptation after proximal enterectomy in rats. METHODS: Wistar rats, aged eight weeks, underwent 60% proximal resection or transection and received by orogastric intubation either 1 mg/g body wt per day lyophilised S boulardii or the vehicle for seven days. The effects on ileal mucosal adaptation were assessed eight days after surgery. RESULTS: Compared with transection, resection resulted in mucosal hyperplasia with significant decreases in the specific and total activities of sucrase, lactase, and maltase. Treatment of resected animals with S boulardii had no effect on mucosal hyperplasia but did upgrade disaccharidase activities to the levels of the transected group. Enzyme stimulation by S boulardii was associated with significant increases in diamine oxidase activity and mucosal polyamine concentrations. Likewise, sodium dependent D-glucose uptake by brush border membrane vesicles, measured as a function of time and glucose concentration in the incubation medium, was significantly (p<0.05) increased by 81% and three times respectively in the resected group treated with S boulardii. In agreement with this, expression of the sodium/glucose cotransporter-1 in brush border membranes of resected rats treated with S boulardii was enhanced twofold compared with resected controls. CONCLUSION: Oral administration of S boulardii soon after proximal enterectomy improves functional adaptation of the remnant ileum.  (+info)

Physiological roles of gammadelta T-cell receptor intraepithelial lymphocytes in cytoproliferation and differentiation of mouse intestinal epithelial cells. (4/153)

In this study we aimed to elucidate the physiological role of gammadelta intraepithelial lymphocytes (IEL) in the mouse intestine. For this purpose, we used T-cell receptor (TCR) Vgamma4/Vdelta5 transgenic mice (KN 6 Tg: BALB/c background, H-2d), and compared the immunological and physiological characteristics of the intestinal tracts of KN 6 Tg and non-transgenic (non-Tg) littermates. In KN 6 Tg littermates, 95% of small intestinal (SI) and large intestinal (LI) IEL expressed gammadelta TCR, and their TCR was replaced by Tg gammadelta TCR. In these mice, class II major histocompatibility complex (MHC) expression was up-regulated in the SI epithelium, compared with the non-Tg littermates, under specific pathogen-free (SPF) conditions. Competitive reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that the mRNAs of the I-Ealpha chain on the SI epithelial cells was higher in KN 6 Tg than in non-Tg littermates. However, in the LI, class II MHC molecules were not expressed in either KN 6 Tg or non-Tg littermates. The epithelial cell mitotic index in the SI, but not in the LI, was higher in KN 6 Tg than in non-Tg littermates under SPF conditions. However, differentiation markers for SI epithelial cells, such as alkaline phosphatase and disaccharidase (lactase, maltase and sucrase) activities, were similar in KN 6 Tg and non-Tg littermates. MHC class II molecule expression on the SI epithelium was absent in germ-free (GF) Tg mice, but was induced under SPF conditions, coinciding with the increase of interferon-gamma (IFN-gamma) mRNA in gammadelta TCR SI-IEL. These findings suggest that gammadelta TCR IEL regulate epithelial cell regeneration and class II MHC expression, but not cell differentiation in the SI. However, these functions were not observed in the gammadelta TCR IEL in the LI. In addition, the activation step in the gammadelta TCR SI-IEL is dependent on the presence of gut microflora.  (+info)

Bifidobacterium animalis protects intestine from damage induced by zinc deficiency in rats. (5/153)

We investigated the potential beneficial effects of Bifidobacterium animalis on intestinal damage using zinc-deficient (ZD) rats as a model for intestinal alterations. The ZD rats were fed diets containing 1 mg Zn/kg for 20 (ZD(20)) or 40 (ZD(40)) d to induce damage that differed in severity. Subgroups of these rats, the ZD(20) + B and ZD(40) + B groups, received a suspension of B. animalis (3.5 x 10(8) colony forming units) daily for the last 10 d. Another subgroup, the ZD(40) + B + 7 d group, was fed the ZD diet for 7 d after the B. animalis treatment period. Zinc deficiency induced ulcerations, edema, inflammatory cell infiltration and dilatation of blood vessels in duodenum, jejunum and ileum, with increasing severity between 20 and 40 d of zinc deficiency. The mucosa of the ZD(20) + B group was well preserved, and most of the morphologic alterations induced by zinc deficiency were normalized in the ZD(40) + B group. The high fecal concentrations of B. animalis in the ZD(40) + B and ZD(40) + B + 7 d groups indicate that these bifidobacteria survived passage through the gastrointestinal tract and proliferated. Electron microscopy confirmed the elevated numbers of bifidobacteria in cecum. Treatment with B. animalis resulted in greater epithelial cell proliferation and disaccharidase activities in the ZD(40) + B group compared with the ZD(40) group. These findings indicate that B. animalis can protect the intestine from alterations induced by zinc deficiency, suggesting that this bacterium may play a role in intestinal mucosal defense.  (+info)

Acetic acid suppresses the increase in disaccharidase activity that occurs during culture of caco-2 cells. (6/153)

To understand how blood glucose level is lowered by oral administration of vinegar, we examined effects of acetic acid on glucose transport and disaccharidase activity in Caco-2 cells. Cells were cultured for 15 d in a medium containing 5 mmol/L of acetic acid. This chronic treatment did not affect cell growth or viability, and furthermore, apoptotic cell death was not observed. Glucose transport, evaluated with a nonmetabolizable substrate, 3-O-methyl glucose, also was not affected. However, the increase of sucrase activity observed in control cells (no acetic acid) was significantly suppressed by acetic acid (P < 0.01). Acetic acid suppressed sucrase activity in concentration- and time-dependent manners. Similar treatments (5 mmol/L and 15 d) with other organic acids such as citric, succinic, L-maric, L-lactic, L-tartaric and itaconic acids, did not suppress the increase in sucrase activity. Acetic acid treatment (5 mmol/L and 15 d) significantly decreased the activities of disaccharidases (sucrase, maltase, trehalase and lactase) and angiotensin-I-converting enzyme, whereas the activities of other hydrolases (alkaline phosphatase, aminopeptidase-N, dipeptidylpeptidase-IV and gamma-glutamyltranspeptidase) were not affected. To understand mechanisms underlying the suppression of disaccharidase activity by acetic acid, Northern and Western analyses of the sucrase-isomaltase complex were performed. Acetic acid did not affect the de novo synthesis of this complex at either the transcriptional or translational levels. The antihyperglycemic effect of acetic acid may be partially due to the suppression of disaccharidase activity. This suppression seems to occur during the post-translational processing.  (+info)

Relation of the disaccharidases in the small intestine of the rat to the degree of experimentally induced iron-deficiency anemia. (7/153)

Hypolactasia associated with severe iron-deficiency anemia has been reported in several studies. The objective of the present study was to determine whether hypolactasia is associated with the degree and duration of iron-deficiency anemia. Newly weaned male Wistar rats were divided into a control group receiving a diet supplemented with iron (C) and an experimental group (E) receiving a diet not supplemented with iron (iron-deficiency diet). The animals were studied on the 3rd, 5th, 7th, 14th, 21st, 28th and 35th days of the experiment, when overall and iron nutritional status and disaccharidase activity in the small intestine were determined by the Dahlqvist method. A reduction in weight occurred in the anemic animals starting on the 5th day of the study. Anemia was present in the experimental animals, with a progressive worsening up to the 14th day (hemoglobin: C = 13.27 and E = 5.37) and stabilizing thereafter. Saccharase and maltase activities did not differ significantly between groups, whereas lactase showed a significant reduction in total (TA) and specific activity (SA) in the anemic animals starting on the 21st day of the study. Median lactase TA for the C and E groups was 2.27 and 1.25 U on the 21st day, 2.87 and 1. 88 U on the 28th day, and 4.20 and 1.59 U on the 35th day, respectively. Median lactase SA was 0.31 and 0.20 U/g wet weight on the 21st day, 0.39 and 0.24 U/g wet weight on the 28th day, and 0.42 and 0.23 U/g wet weight on the 35th day, respectively. These findings suggest a relationship between the enzymatic alterations observed and both the degree and duration of the anemic process. Analysis of other studies on intestinal disaccharidases in anemia suggests that the mechanism of these changes may be functional, i.e., that the enterocytes may suffer a reduction in their ability to synthesize these enzymes.  (+info)

Determinants of translocation and folding of TreF, a trehalase of Escherichia coli. (8/153)

One isoform of trehalase, TreF, is present in the cytoplasm and a second, TreA, in the periplasm. To study the questions of why one enzyme is exported efficiently and the other is not and whether these proteins can fold in their nonnative cellular compartment, we fused the signal sequence of periplasmic TreA to cytoplasmic TreF. Even though this TreF construct was exported efficiently to the periplasm, it was not active. It was insoluble and degraded by the periplasmic serine protease DegP. To determine why TreF was misfolded in the periplasm, we isolated and characterized Tre(+) revertants of periplasmic TreF. To further characterize periplasmic TreF, we used a genetic selection to isolate functional TreA-TreF hybrids, which were analyzed with respect to solubility and function. These data suggested that a domain located between residues 255 and 350 of TreF is sufficient to cause folding problems in the periplasm. In contrast to TreF, periplasmic TreA could fold into the active conformation in its nonnative cellular compartment, the cytoplasm, after removal of its signal sequence.  (+info)

Indeed, this is exactly what happens in rodents, pigs and, for the most part, humans. In both pigs and humans, lactase activity is first observed early in gestation (e.g. 8-9 weeks in human gestation) and rises rather dramatically during the third trimester to achieve high levels during the first week of life. The top figure to the right depicts brush border lactase concentrations in different regions of the neonatal pig intestine, from one through six weeks of age. Note the steady decline in lactase concentration throughout the small intestine, a pattern seen in essentially all animals studied. The bottom figure to the right shows the inverse relationship between lactase and sucrase concentrations in the small intestine of young rats. In humans, the change in sucrase expression is less dramatic, and sucrase concentrations are relatively stable from birth through adulthood. There are numerous differences in dissacharidase activity among species. As another example, and in contrast to rats, ...
Disaccharidase definition, an enzyme that catalyzes the hydrolysis of disaccharides, as sucrose or lactose, to produce monosaccharides, as fructose or glucose. See more.
OVERVIEW: What every practitioner needs to know Are you sure your patient has disaccharidase deficiencies? What are the typical findings for this disease? Disaccharidase deficiencies are caused by the decreased hydrolysis of the disaccharides (double-sugars) by the disaccharidase enzymes (lactase; maltase-glucoamylase; sucrase-isomaltase; palatinase and trehalase). These enzymes are localized in the brush border membrane of…. ...
Disaccharides: Simple sugars or monosaccharides are directly absorbed into the bloodstream, while disaccharides are two single sugars that are linked together. Grains contain disaccharide that needs to be broken down first before being absorbed in the bloodstream. Disaccharide is broken down into monosaccharide by enzymes called disaccharidases which are present in the brush like border called villi of the small intestine wall. Any kind of inflammatory damage to the cells in the small intestine lead to disaccharidase enzyme not being produced and lead to disaccharide intolerance. Disaccharide intolerance is the inability to break apart the disaccharide into two single sugars and absorb them. This often leads to uncomfortable digestive symptoms. ...

Lactulose 65% Syrup About Lactulose A synthetic Disaccharide, Osmotic Laxative, Ammonium Detoxicant. Mechanism of Action of Lactulose Laxative: Lactulose is a synthetic disaccharide of galactose and fructose that resist intestinal disaccharidase activity. The sugars are joined by a beta glycosidic linkage and are resistant to hydrolysis by human digestive enzymes. Lactulose is fermented by a limited number of colonic bacteria. This can lead to changes in the colonic ecosystem in favor of some bacteria, such as lactobacilli and bifidobacteria, which may confer some health benefits. The products of fermentation include lactic acid and small-chain fatty acids. Degradation to short chain fatty acids also increases the osmotic pressure in the intestinal lumen. It also cause an increase in fecal volume due to intraluminal water retention and stimulate colonic propulsive motility result in increased fecal bulk and stimulation of peristalsis.

The fact that HFCS consists mainly of two monosaccharides, while sucrose is a disaccharide, may also not be insignificant. In order to be absorbed as its constituent monosaccharides, sucrose must first be hydrolyzed by intestinal mucosal disaccharidase enzymes. Thus, the absorption of fructose from sucrose might be considerably slower than the absorption of the free fructose present in HFCS. That possibility is supported by studies in which serum fructose concentrations increased to a greater extent after feeding free fructose than after feeding the same amount of fructose in the form of sucrose ...
Recently in Gut, a coding sucrase-isomaltase (SI) variant (15Phe at single nucleotide polymorphism rs9290264) with 35% reduced disaccharidase activity was reported to increase IBS risk and to correlate with more frequent stools. These observations were not assessed in relation to key dietary factors including carbohydrate (ie, SI substrates) consumption.1 Here, we studied two large German population-based cross-sectional cohorts, namely PopGen (n=639; average age 61.4; 44.8% female) and FoCus (n=759; average age 53.0; 58.5% female), with available genotype (genome-wide arrays), dietary (12-month food frequency questionnaire, FFQ), faecal microbiota (16S sequencing) and IBS status (self-reported from questionnaire) data, as previously described in detail.2-4 In a combined age/sex/body mass index (BMI)-adjusted logistic regression analysis of the two data sets, carriers of the 15Phe variant (52.86%) reported IBS significantly more often than non-carriers (3.69% vs 1.84%, respectively; P=0.044, ...
Trigonella foenum-graecum (fenugreek) has been used in traditional medicine for the treatment of diabetes. Fenugreek has been demonstrated to lower blood glucose in response to a glucose load while leaving the levels of serum insulin unaffected in rodents. This effect of lowering blood sugar without changing insulin levels demonstrates improved insulin action. Fenugreek has also been shown to decrease glucose absorption by inhibiting intestinal disaccharidases. Fenugreek decreases glycohemoglobin in diabetic rodents. An amino acid extracted from fenugreek seeds, 4-hydroxyisoleucine, decreases glucose and insulin in diabetic rodents, improves glucose tolerance and stimulates insulin secretion from isolated pancreatic rodent islets.. Fenugreek imparts a bitter taste to products into which it is placed, and this property has limited its use in treating diabetes. Dr. Losso and his associates developed a process that allows incorporation of fenugreek into bread and other bakery goods without ...

It secretes a leucine aminopeptidase that appears to support against allergies to dietary proteins following acute gastroenteritis. S. boulardii augments the intestinal absorption of D-glucose coupled with sodium that may enhance uptake of water and electrolytes during diarrhea. It increases stool concentrations of short-chain fatty acids that nourish colon mucosal cells. It modulates immunity by boosting intestinal secretion of IgA and increasing crypt cell immuno-globulin receptors. It inhibits inflammatory cytokine pathways and secretes a factor that blocks C. difficile toxin A activities ...

Erwinia rhapontici is able to convert sucrose into isomaltulose (palatinose, 6-O-α-d-glucopyranosyl-d-fructose) and trehalulose (1-O-α-d-glucopyranosyl-d-fructose) by the activity of a sucrose isomerase. These sucrose isomers cannot be metabolized by plant cells and most other organisms and therefore are possibly advantageous for the pathogen. This view is supported by the observation that in vitro yeast invertase activity can be inhibited by palatinose, thus preventing sucrose consumption. Due to the lack of genetic information, the role of sucrose isomers in pathogenicity has not been evaluated. Here we describe for the first time the cloning and characterization of the palatinose (pal) genes fromErwinia rhapontici. To this end, a 15-kb chromosomal DNA fragment containing nine complete open reading frames (ORFs) was cloned. The pal gene products of Erwinia rhapontici were shown to be homologous to proteins involved in uptake and metabolism of various sugars from other microorganisms. ...

Gastrointestinal disturbances are commonly reported in children with autism, complicate clinical management, and may contribute to behavioral impairment. Reports of deficiencies in disaccharidase enzymatic activity and of beneficial responses to probiotic and dietary therapies led us to survey gene expression and the mucoepithelial microbiota in intestinal biopsies from children with autism and gastrointestinal disease and children with gastrointestinal disease alone. Ileal transcripts encoding disaccharidases and hexose transporters were deficient in children with autism, indicating impairment of the primary pathway for carbohydrate digestion and transport in enterocytes. Deficient expression of these enzymes and transporters was associated with expression of the intestinal transcription factor, CDX2. Metagenomic analysis of intestinal bacteria revealed compositional dysbiosis manifest as decreases in Bacteroidetes, increases in the ratio of Firmicutes to Bacteroidetes, and increases in

This gene encodes lysosomal alpha-glucosidase, which is essential for the degradation of glycogen to glucose in lysosomes. Different forms of acid alpha-glucosidase are obtained by proteolytic processing. Defects in this gene are the cause of glycogen storage disease II, also known as Pompe disease, which is an autosomal recessive disorder with a broad clinical spectrum. Three transcript variants encoding the same protein have been found for this gene.[6] ...
... catalyzes the hydrolysis of the glycosidic bonds to terminal non-reducing residues in beta-D-glucosides and oligosaccharides, with release of glucose.[2] Synonyms, derivatives, and related enzymes include gentiobiase, cellobiase, emulsin,[3] elaterase, aryl-beta-glucosidase, beta-D-glucosidase, beta-glucoside glucohydrolase, arbutinase, amygdalinase, p-nitrophenyl beta-glucosidase, primeverosidase, amygdalase, linamarase, salicilinase, and beta-1,6-glucosidase. Cellulose is a polymer composed of beta-1,4-linked glucosyl residues. Cellulases (endoglucanases), cellobiosidases (exoglucanases), and beta-glucosidases are required by organisms (some fungi, bacteria) that can consume it. These enzymes are powerful tools for degradation of plant cell walls by pathogens and other organisms consuming plant biomass. ...
... is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides. The name is also used for any naturally occurring mixture or complex of various such enzymes, that act serially or synergistically to decompose cellulosic material. Cellulases break down the cellulose molecule into monosaccharides ("simple sugars") such as beta-glucose, or shorter polysaccharides and oligosaccharides. Cellulose breakdown is of considerable economic importance, because it makes a major constituent of plants available for consumption and use in chemical reactions. The specific reaction involved is the hydrolysis of the 1,4-beta-D-glycosidic linkages in cellulose, hemicellulose, lichenin, and cereal beta-D-glucans. Because cellulose molecules bind strongly to each other, cellulolysis is relatively difficult compared to the breakdown of other polysaccharides such as starch.[2] Most mammals have only ...
Sucrose intolerance (also known as congenital sucrase-isomaltase deficiency (CSID), genetic sucrase-isomaltase deficiency (GSID), or sucrase-isomaltase deficiency) occurs when sucrase is not being secreted in the small intestine. With sucrose intolerance, the result of consuming sucrose is excess gas production and often diarrhea and malabsorption. Lactose intolerance is a related disorder that reflects an individual's inability to hydrolyze the disaccharide lactose. Sucrase is secreted by the tips of the villi of the epithelium in the small intestine. Its levels are reduced in response to villi-blunting events such as celiac sprue and the inflammation associated with the disorder. The levels increase in pregnancy, lactation, and diabetes as the villi hypertrophy. ...
... inhibitors are useful for combating influenza infection: zanamivir, administered by inhalation; oseltamivir, administered orally; peramivir administered parenterally, that is through intravenous or intramuscular injection; and laninamivir which is in phase III clinical trials. There are two major proteins on the surface of influenza virus particles. One is the lectin haemagglutinin protein with three relatively shallow sialic acid-binding sites and the other is enzyme sialidase with the active site in a pocket. Because of the relative deep active site in which low-molecular-weight inhibitors can make multiple favorable interactions and approachable methods of designing transition-state analogues in the hydrolysis of sialosides, the sialidase becomes more attractive anti-influenza drug target than the haemagglutinin.[9] After the X-ray crystal structures of several influenza virus sialidases were available, the structure-based inhibitor design was applied to discover potent ...
... is an enzyme that catalyzes the hydrolysis (breakdown) of sucrose (table sugar) into fructose and glucose.[1][2] Alternative names for invertase include EC 3.2.1.26, saccharase, glucosucrase, beta-h-fructosidase, beta-fructosidase, invertin, sucrase, maxinvert L 1000, fructosylinvertase, alkaline invertase, acid invertase, and the systematic name: beta-fructofuranosidase. The resulting mixture of fructose and glucose is called inverted sugar syrup. Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertases cleave the O-C(fructose) bond, whereas the sucrases cleave the O-C(glucose) bond.[3] For industrial use, invertase is usually derived from yeast. It is also synthesized by bees, which use it to make honey from nectar. Optimal temperature at which the rate of reaction is at its greatest is 60 °C and an optimum pH of 4.5.[3] Typically, sugar is inverted with sulfuric acid.[dubious - discuss] ...
Saccharides are a food source rich in energy. Large polymers such as starch are partially hydrolyzed in the mouth by the enzyme amylase before being cleaved further into sugars. Many mammals have seen great expansions in the copy number of the amylase gene. These duplications allow for the pancreatic amylase AMY2 to re-target to the salivary glands, allowing animals to detect starch by taste and to digest starch more efficiently and in higher quantities. This has happened independently in mice, rats, dogs, pigs, and most importantly, humans after the agricultural revolution.[20] Following the agricultural revolution 12,000 years ago, human diet began to shift more to plant and animal domestication in place of gathering and hunting. Starch has become a staple of the human diet. Despite the obvious benefits, early humans did not possess salivary amylase, a trend that is also seen in evolutionary relatives of the human, such as chimpanzees and bonobos, who possess either one or no copies of the ...
... s are predicted to gain increasing roles as catalysts in biorefining applications in the future bioeconomy.[14] These enzymes have a variety of uses including degradation of plant materials (e.g., cellulases for degrading cellulose to glucose, which can be used for ethanol production), in the food industry (invertase for manufacture of invert sugar, amylase for production of maltodextrins), and in the paper and pulp industry (xylanases for removing hemicelluloses from paper pulp). Cellulases are added to detergents for the washing of cotton fabrics and assist in the maintenance of colours through removing microfibres that are raised from the surface of threads during wear. In organic chemistry, glycoside hydrolases can be used as synthetic catalysts to form glycosidic bonds through either reverse hydrolysis (kinetic approach) where the equilibrium position is reversed; or by transglycosylation (kinetic approach) whereby retaining glycoside hydrolases can catalyze the transfer ...
