A family of glycosidases that hydrolyse crystalline CELLULOSE into soluble sugar molecules. Within this family there are a variety of enzyme subtypes with differing substrate specificities that must work together to bring about complete cellulose hydrolysis. They are found in structures called CELLULOSOMES.
High molecular weight polysaccharides present in the cell walls of all plants. Pectins cement cell walls together. They are used as emulsifiers and stabilizers in the food industry. They have been tried for a variety of therapeutic uses including as antidiarrheals, where they are now generally considered ineffective, and in the treatment of hypercholesterolemia.
The most abundant natural aromatic organic polymer found in all vascular plants. Lignin together with cellulose and hemicellulose are the major cell wall components of the fibers of all wood and grass species. Lignin is composed of coniferyl, p-coumaryl, and sinapyl alcohols in varying ratios in different plant species. (From Merck Index, 11th ed)
A group of enzymes that catalyze the hydrolysis of alpha- or beta-xylosidic linkages. EC 22.214.171.124 catalyzes the endo-hydrolysis of 1,4-beta-D-xylosidic linkages; EC 126.96.36.199 catalyzes the endo-hydrolysis of 1,3-beta-D-xylosidic linkages; EC 188.8.131.52 catalyzes the exo-hydrolysis of 1,4-beta-D-linkages from the non-reducing termini of xylans; and EC 184.108.40.206 catalyzes the exo-hydrolysis of 1,3-beta-D-linkages from the non-reducing termini of xylans. Other xylosidases have been identified that catalyze the hydrolysis of alpha-xylosidic bonds.

Microscopy, Electron, Scanning
Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
The region of the stem beneath the stalks of the seed leaves (cotyledons) and directly above the young root of the embryo plant. It grows rapidly in seedlings showing epigeal germination and lifts the cotyledons above the soil surface. In this region (the transition zone) the arrangement of vascular bundles in the root changes to that of the stem. (From Concise Dictionary of Biology, 1990)
The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach. (From Black's Veterinary Dictionary, 17th ed)
Uridine Diphosphate Glucose
A key intermediate in carbohydrate metabolism. Serves as a precursor of glycogen, can be metabolized into UDPgalactose and UDPglucuronic acid which can then be incorporated into polysaccharides as galactose and glucuronic acid. Also serves as a precursor of sucrose lipopolysaccharides, and glycosphingolipids.
The influence of a diet rich in wheat fibre on the human faecal flora. (1/2543)The effect on the faecal flora of adding wheat fibre to a controlled diet in four healthy volunteers for a 3-week period has been observed. No change in the concentration of the bacteria in the bacterial groups counted was found, although there was a slight increase in total output associated with increased faecal weight. The predominant organisms in all subjects were non-sporing anaerobes, but the dominant species in each subject was different and was unaffected by changing the diet. Similarly, the concentration of faecal beta-glucuronidase detected in two subjects was unaltered and the concentration of clostridia able to dehydrogenate the steroid nucleus found in one subject was unaltered. It is suggested that the faecal microflora is not primarily controlled by the presence of undigested food residues in the large bowel. (+info)
Citric acid production from xylan and xylan hydrolysate by semi-solid culture of Aspergillus niger. (2/2543)Citric acid production from xylan and xylan hydrolysate was done by Aspergillus niger Yang no. 2 cultivated in a semi-solid culture using bagasse as a carrier. Yang no. 2 produced 72.4 g/l and 52.6 g/l of citric acid in 5 d from 140 g/l of xylose and arabinose, respectively. Yang no. 2 produced 51.6 g/l of citric acid in 3 d from a concentrated xylan hydrolysate prepared by cellulase treatment, containing 100 g/l of reducing sugars. Moreover, Yang no. 2 directly produced 39.6 g/l of citric acid maximally in 3 d from 140 g/l of xylan. (+info)
Lignocellulose degradation by Phanerochaete chrysosporium: purification and characterization of the main alpha-galactosidase. (3/2543)The main alpha-galactosidase was purified to homogeneity, in 30% yield, from a solid culture of Phanerochaete chrysosporium on 1 part wheat bran/2 parts thermomechanical softwood pulp. It is a glycosylated tetramer of 50 kDa peptide chains, which gives the N-terminal sequence ADNGLAITPQMG(?W)NT(?W)NHFG(?W)DIS(?W)DTI. It is remarkably stable, with crude extracts losing no activity over 3 h at 80 degrees C, and the purified enzyme retaining its activity over several months at 4 degrees C. The kinetics of hydrolysis at 25 degrees C of various substrates by this retaining enzyme were measured, absolute parameters being obtained by active-site titration with 2',4',6'-trinitrophenyl 2-deoxy-2, 2-difluoro-alpha-D-galactopyranoside. The variation of kcat/Km for 1-naphthyl-alpha-D-galactopyranoside with pH is bell-shaped, with pK1=1.91 and pK2=5.54. The alphaD(V/K) value for p-nitrophenyl-alpha-D-glucopyranoside is 1.031+/-0.007 at the optimal pH of 3.75 and 1.114+/-0.006 at pH7.00, indicating masking of the intrinsic effect at optimal pH. There is no alpha-2H effect on binding galactose [alphaD(Ki)=0.994+/-0.013]. The enzyme hydrolyses p-nitrophenyl beta-L-arabinopyranoside approximately 510 times slower than the galactoside, but has no detectable activity on the alpha-D-glucopyranoside or alpha-D-mannopyranoside. Hydrolysis of alpha-galactosides with poor leaving groups is Michaelian, but that of substrates with good leaving groups exhibits pronounced apparent substrate inhibition, with Kis values similar to Km values. We attribute this to the binding of the second substrate molecule to a beta-galactopyranosyl-enzyme intermediate, forming an E.betaGal. alphaGalX complex which turns over slowly, if at all. 1-Fluoro-alpha-D-galactopyranosyl fluoride, unlike alpha-D-galactopyranosyl fluoride, is a Michaelian substrate, indicating that the effect of 1-fluorine substitution is greater on the first than on the second step of the enzyme reaction.

The selective isolation of the uterine oestradiol-receptor complex by binding to oligo(dT)-cellulose. The mediation of an essential activator in the transformation of cytosol receptor. (4/2543)The [3H]oestradiol-receptor complex was selectively isolated from rat uterus cytosol by column chromatography on oligo(dT)-cellulose. Optimal conditions are described for the binding of the complex to oligo(dT)-cellulose, which is shown to be similar to its binding to DNA-cellulose. The cytosol complex has an apparent mol. wt. of 50,000-60,000 in high salt concentrations, as determined by Sephadex G-100 chromatography. This corresponds to the 4S cytoplasmic oestradiol receptor. In binding to oligo(dT)-cellulose the receptor is transformed into a form with an apparent mol.wt. of 100,000-120,000, corresponding to the 5S nuclear receptor complex. This transformation mimics the conversion in vivo of the cytoplasmic oestradiol receptor into the nuclear form. The binding of the complex to oligo(dT)-cellulose as a 5S nuclear form is unequivocally demonstrated to require the mediation of an activating present in the cytosol. The requirement for an activating factor is discussed in relation to reports that nuclear binding of the oestradiol-receptor complex is not dictated solely by the availability of the cytoplasmic oestradiol receptor.

Molecular cloning and expression of the novel fungal beta-glucosidase genes from Humicola grisea and Trichoderma reesei. (5/2543)A novel fungal beta-glucosidase gene (bgl4) and its homologue (bgl2) were cloned from the cellulolytic fungi Humicola grisea and Trichoderma reesei, respectively. The deduced amino acid sequences of H. grisea BGL4 and T. reesei BGL2 comprise 476 and 466 amino acids, respectively, and share 73.1% identity. These beta-glucosidases show significant homology to plant beta-glucosidases belonging to the beta-glucosidase A (BGA) family. Both genes were expressed in Aspergillus oryzae, and the recombinant beta-glucosidases were purified. Recombinant H. grisea BGL4 is a thermostable enzyme compared with recombinant T. reesei BGL2. In addition to beta-glucosidase activity, recombinant H. grisea BGL4 showed a significant level of beta-galactosidase activity, while recombinant T. reesei BGL2 showed weak beta-galactosidase activity. Cellulose saccharification by Trichoderma cellulases was improved by the addition of recombinant H. grisea BGL4. (+info)
Cellulolytic enzymes in culture filtrates of Rhizoctonia lamellifera. (6/2543)During growth in a liquid culture containing a single soluble or an insoluble cellulosic carbon source, Rhizoctonia lamellifera released cellulolytic enzymes into the medium. These enzymes were separated by gel filtration and ion-exchange chromatography into seven components, three of high and four of low molecular weight. One of the components had the character of a C1 cellulase. When the components were combined they released more reducing sugars from cellulosic substrates than when used singly. (+info)
Calculus disease of the urinary tract at a district hospital. (7/2543)At a District General Hospital the organization of a clinic for the investigation and treatment of patients with calculus disease of the urinary tract is described. The way in which such a clinic may be orgainzed is discussed and the results presented. In patients with idiopathic hypercalciuria, sodium cellulose phosphate causes a significant reduction in urinary calcium levels when used in such a clinic. (+info)
Identification of a nucleic acid binding domain in eukaryotic initiation factor eIFiso4G from wheat. (8/2543)Higher plants have two complexes that bind the m7G-cap structure of mRNA and mediate interactions between mRNA and ribosomal subunits, designated eIF4F and eIFiso4F. Both complexes contain a small subunit that binds the 5'-cap structure of mRNA, and a large subunit, eIF4G or eIFiso4G, that binds other translation factors and RNA. Sequence-specific proteases were used to cleave native cap-binding complexes into structural domains, which were purified by affinity chromatography. We show here that eIFiso4G contains a central protease-resistant domain that binds specifically to nucleic acids. This domain spans Gln170 to Glu443 and includes four of the six homology blocks shared by eIFiso4G and eIF4G. A slightly shorter overlapping sequence, from Gly202 to Lys445, had no nucleic acid binding activity, indicating that the N-terminal end of the nucleic acid binding site lies within Gln170 to Arg201. The binding of the central domain and native eIFiso4F to RNA homopolymers and double- and single-stranded DNAs was studied. Both molecules had highest affinity for poly(G) and recognized single- and double-stranded sequences. (+info)
