Action of chondroitinases. II. Numerical calculation of the degree of multiple attack. (1/149)

Further investigation was carried out on the action patterns of two chondroitinase-AC [EC 4.2.2.5.] preparations obtained from Arthrobacter aurescens and Flavobacterium heparinum. To infer the action patterns of the chondroitinases, we proposed a new method for the calculation of the degree of multiple attack, based on the concept established by Robyt and French ((1967) Arch. Biochem. Biophys. 122, 8-16). It was shown that the degree of multiple attack (DM) is represented by the ratio of the initial velocity of number-average degree of scission to that of viscosity-average degree of scission. By this method, DM for A-Chase was estimated to be 3.03 and for F-chase, 1.31.  (+info)

Substrate specificity studies of Flavobacterium chondroitinase C and heparitinases towards the glycosaminoglycan--protein linkage region. Use of a sensitive analytical method developed by chromophore-labeling of linkage glycoserines using dimethylaminoazobenzenesulfonyl chloride. (2/149)

Bacterial chondroitinases and heparitinases are potentially useful tools for structural studies of chondroitin sulfate and heparin/heparan sulfate. Substrate specificities of Flavobacterium chondroitinase C, as well as heparitinases I and II, towards the glycosaminoglycan-protein linkage region -HexA-HexNAc-GlcA-Gal-Gal-Xyl-Ser (where HexA represents glucuronic acid or iduronic acid and HexNAc represents N-acetylgalactosamine or N-acetylglucosamine) were investigated using various structurally defined oligosaccharides or oligosaccharide-serines derived from the linkage region. In the case of oligosaccharide-serines, they were labeled with a chromophore dimethylaminoazobenzenesulfonyl chloride (DABS-Cl), which stably reacted with the amino group of the serine residue and rendered high absorbance for microanalysis. Chondroitinase C cleaved the GalNAc bond of the pentasaccharides or hexasaccharides derived from the linkage region of chondroitin sulfate chains and tolerated sulfation of the C-4 or C-6 of the GalNAc residue and C-6 of the Gal residues, as well as 2-O-phosphorylation of the Xyl residue. In contrast, it did not act on the GalNAc-GlcA linkage when attached to a 4-O-sulfated Gal residue. Heparitinase I cleaved the innermost glucosaminidic bond of the linkage region oligosaccharide-serines of heparin/heparan sulfate irrespective of substitution by uronic acid, whereas heparitinase II acted only on the glucosaminidic linkages of the repeating disaccharide region, but not on the innermost glucosaminidic linkage. These defined specificities of chondroitinase C, as well as heparitinases I and II, will be useful for preparation and structural analysis of the linkage oligosaccharides.  (+info)

Sulfate incorporation from ascorbate 2-sulfate into chondroitin sulfate by embryonic chick cartilage epiphyses. (3/149)

Radioactivity was significantly incorporated from ascorbate 2-[35S]sulfate into chondroitin sulfate by embryonic chick cartilage epiphyses. The extent of incorporation was comparable with that from inorganic [35S]sulfate. The radioactive chondroitin sulfate formed from ascorbate 2-[35S]sulfate gave two radioactive disaccharides on chondroitinase-ABC [EC 4.2.2.4] digestion. The incorporation was markedly decreased by inorganic sulfate. The time course of incorporation from ascorbate 2-[35S]sulfate and inorganic [35S]sulfate into chondroitin sulfate and the constituent disaccharides suggest that the incorporation rates from the two radioactive substances are different.  (+info)

Sulphation heterogeneity in the trisaccharide (GalNAcSbeta1, 4GlcAbeta1,3GalNAcS) isolated from the non-reducing terminal of human aggrecan chondroitin sulphate. (4/149)

We report here the isolation and sulphation isomer analyses of trisaccharides GalNAcS(beta1,4)GlcA(beta1,3)GalNAcS (in which S indicates sulphate) derived from the non-reducing termini of aggrecan chondroitin sulphate. Rat chondrosarcoma and human aggrecans were digested for 1 h at 37 degrees C with 30 micro-units of endo-chondroitinase ABC per microgram of chondroitin sulphate, and trisaccharides were isolated from the digests by ToyoPearl HW40S gel-filtration chromatography. Four trisaccharide species were identified; their sulphation isomer compositions, as determined by digestion with chondroitinase ACII and fluorescence-based ion-exchange HPLC, were GalNAc4Sbeta1,4GlcAbeta1,3GalNAc4S, GalNAc4Sbeta1,4GlcAbeta1,3GalNAc6S, GalNAc4,6Sbeta1,4GlcAbeta1, 3GalNAc4S and GalNAc4,6Sbeta1,4GlcAbeta1,3GalNAc6S. The abundances of such sequences in chondroitin sulphate on aggrecan from normal (foetal to 72 years of age) and from osteoarthritic human knee cartilages were also established. The results showed that non-reducing terminal GalNAc4S or GalNAc4,6S can be linked to either a 4-sulphated or a 6-sulphated disaccharide, suggesting that the sulphation of the last disaccharide might not have a direct effect on the specificity of chondroitin sulphate terminal GalNAc sulphotransferases. Furthermore, for each aggrecan preparation examined, the 4S-to-6S ratio of all chain interior disaccharides was equivalent to that in the last repeating disaccharides at the non-reducing terminus, suggesting that neither chondroitin 4-sulphotransferase nor chondroitin 6-sulphotransferase shows preferential activity near the chain terminus.  (+info)

Isolation and expression in Escherichia coli of cslA and cslB, genes coding for the chondroitin sulfate-degrading enzymes chondroitinase AC and chondroitinase B, respectively, from Flavobacterium heparinum. (5/149)

In medium supplemented with chondroitin sulfate, Flavobacterium heparinum synthesizes and exports two chondroitinases, chondroitinase AC (chondroitin AC lyase; EC 4.2.2.5) and chondroitinase B (chondroitin B lyase; no EC number), into its periplasmic space. Chondroitinase AC preferentially depolymerizes chondroitin sulfates A and C, whereas chondroitinase B degrades only dermatan sulfate (chondroitin sulfate B). The genes coding for both enzymes were isolated from F. heparinum and designated cslA (chondroitinase AC) and cslB (chondroitinase B). They were found to be separated by 5.5 kb on the chromosome of F. heparinum, transcribed in the same orientation, but not linked to any of the heparinase genes. In addition, the synthesis of both enzymes appeared to be coregulated. The cslA and cslB DNA sequences revealed open reading frames of 2,103 and 1,521 bp coding for peptides of 700 and 506 amino acid residues, respectively. Chondroitinase AC has a signal sequence of 22 residues, while chondroitinase B is composed of 25 residues. The mature forms of chondroitinases AC and B are comprised of 678 and 481 amino acid residues and have calculated molecular masses of 77,169 and 53,563 Da, respectively. Truncated cslA and cslB genes have been used to produce active, mature chondroitinases in the cytoplasm of Escherichia coli. Partially purified recombinant chondroitinases AC and B exhibit specific activities similar to those of chondroitinases AC and B from F. heparinum.  (+info)

A fingerprinting method for chondroitin/dermatan sulfate and hyaluronan oligosaccharides. (6/149)

A previously published method for the analysis of glycosaminoglycan disaccharides by high pH anion exchange chromatography (Midura,R.J., Salustri,A., Calabro,A., Yanagishita,M. and Hascall,V.C. (1994), Glycobiology,4, 333-342) has been modified and calibrated for chondroitin and dermatan sulfate oligosaccharides up to hexasaccharide in size and hyaluronan oligosaccharides up to hexadecasaccharide. For hyaluronan oligosaccharides chain length controls elution position; however, for chondroitin and dermatan sulfate oligosaccharides elution times primarily depend upon the level of sulfation, although chain length and hence charge density plays a role. The sulfation position of GalNAc residues within an oligosaccharide is also important in determining its elution position. Compared to 4-sulfation a reducing terminal 6-sulfate retards elution; however, when present on an internal GalNAc residue it is the 4-sulfate containing oligosaccharide which elutes later. These effects allow discrimination between oligosaccharides differing only in the position of GalNAc sulfation. Using this simple methodology, a Dionex CarboPac PA-1 column with NaOH/NaCl eluents and detection by absorbance at 232 nm, a quantitative analytical fingerprint of a chondroitin/dermatan sulfate chain may be obtained, allowing a determination of the abundance of chondroitin sulfate, dermatan sulfate, and hyaluronan along with an analysis of structural features with a linear response to approximately 0.1 nmol. The method may readily be calibrated using either commercial disaccharides or the di- and tetrasaccharide products of a limit digest of commercial chondroitin sulfate by chondroitin ABC endolyase. Commercially available and freshly prepared shark, whale, bovine, and human cartilage chondroitin sulfates have been examined by this methodology and we have confirmed that freshly isolated shark cartilage CS contains significant amounts of the biologically important GlcA2Sbeta(1-3)GalNAc6S structure.  (+info)

Iduronic acid-containing glycosaminoglycans on target cells are required for efficient respiratory syncytial virus infection. (7/149)

Respiratory syncytial virus (RSV) is an important human respiratory pathogen, particularly in infants. Glycosaminoglycans (GAGs) have been implicated in the initiation of RSV infection of cultured cells, but it is not clear what type of GAGs and GAG components are involved, whether the important GAGs are on the virus or the cell, or what the magnitude is of their contribution to infection. We constructed and rescued a recombinant green fluorescent protein (GFP)-expressing RSV (rgRSV) and used this virus to develop a sensitive system to assess and quantify infection by flow cytometry. Evaluation of a panel of mutant Chinese hamster ovary cell lines that are genetically deficient in various aspects of GAG synthesis showed that infection was reduced up to 80% depending on the type of GAG deficiency. Enzymatic removal of heparan sulfate and/or chondroitin sulfate from the surface of HEp-2 cells also reduced infection, and the removal of both reduced infection even further. Blocking experiments in which RSV was preincubated with various soluble GAGs revealed the relative blocking order of: heparin > heparan sulfate > chondroitin sulfate B. Iduronic acid is a component common to these GAGs. GAGs that do not contain iduronic acid, namely, chondroitin sulfate A and C and hyaluronic acid, did not inhibit infection. A role for iduronic acid-containing GAGs in RSV infection was confirmed by the ability of basic fibroblast growth factor to block infection, because basic fibroblast growth factor binds to GAGs containing iduronic acid. Pretreatment of cells with protamine sulfate, which binds and blocks GAGs, also reduced infection. In these examples, infection was reduced by pretreatment of the virus with soluble GAGs, pretreatment of the cells with GAG-binding molecules, pretreatment of the cells with GAG-destroying enzymes or in cells genetically deficient in GAGs. These results establish that the GAGs involved in RSV infection are present on the cell rather than on the virus particle. Thus, the presence of cell surface GAGs containing iduronic acid, like heparan sulfate and chondroitin sulfate B, is required for efficient RSV infection in cell culture.  (+info)

Distribution of sulfated glycosaminoglycans in the animal kingdom: widespread occurrence of heparin-like compounds in invertebrates. (8/149)

Sulfated glycosaminoglycans were isolated from 23 species of 13 phyla of invertebrates and characterized by their electrophoretic migration in three different buffer systems coupled with enzymatic degradation using bacterial heparinase, heparitinases and chondroitinase AC. Heparan sulfate is a ubiquitous compound present in all species analyzed whereas chondroitin sulfate was present in 20 species and heparin-like compounds in 12 species of the invertebrates. The heparin-like compounds were purified from the echinoderm Mellita quinquisperforata (sand dollar) and the crustacean Ucides cordatus (crab) with anticoagulant activities of 60 and 52 IU/mg, respectively. Degradation of these heparins with heparinase produced significant amounts of the trisulfated disaccharide typical of mammalian heparins. This was confirmed by 13C-NMR spectroscopy of the crab heparin. An updated phylogenetic tree of the distribution of sulfated glycosaminoglycans in the animal kingdom is also presented.  (+info)

Tenacibaculum maritimum is a devastating bacterial pathogen of wild and farmed marine fish with a broad host range and a worldwide distribution. We report here the complete genome sequence of the T. maritimum type strain NCIMB 2154T. The genome consists of a 3,435,971-base pair circular chromosome with 2,866 predicted protein-coding genes. Genes encoding the biosynthesis of exopolysaccharides, the type IX secretion system, iron uptake systems, adhesins, hemolysins, proteases, and glycoside hydrolases were identified. They are likely involved in the virulence process including immune escape, invasion, colonization, destruction of host tissues, and nutrient scavenging. Among the predicted virulence factors, type IX secretion-mediated and cell-surface exposed proteins were identified including an atypical sialidase, a sphingomyelinase and a chondroitin AC lyase which activities were demonstrated in vitro.
Purpose: To evaluate the potential of a bioactive coating based on chondroitin sulfate (CS) and tethered epidermal growth factor (EGF) for the improvement of healing around stent-grafts (SG). Methods: The impact of the bioactive coating on cell survival was tested in vitro on human vascular cells using polyethylene terephtalate films (PET) as a substrate. After being transferred onto a more realistic material (expanded poly(tetrafluoroethylene), ePTFE), the durability and mechanical behavior of the coating in addition to cell survival were studied. Preliminary in vivo testing was performed in a canine iliac aneurysm model reproducing type I endoleaks (3 animals with 1 control and 1 bioactive SG for each). Results: The CS and EGF coatings significantly increased survival of human smooth muscle cells and fibroblasts, compared with bare PET or ePTFE (P,.05). The coating also displayed good durability over 30 days according to ELISA and cell-survival tests. The coating did not affect the ...

Glucosamine and chondroitin have been the stepchildren of modern medicine for many years. While their use has skyrocketed due to a mass of supplements on the market, the average family doctor was much more likely to prescribe pharmaceutical concoctions such as Celebrex. In a study presented in November 2015 at a meeting of the American College of Rheumatology, chondroitin dramatically beat Celebrex in a head-to-head trial.. Chondroitin is a component of cartilage. The theory for taking it always has been simple-to provide the body with the building blocks of cartilage, and, just maybe, this would preserve or build cartilage. While the reality of how chondroitin works is a lot more complex, small studies using MRI have shown that chondoitin preserves cartilage. When given along with its cousin glucosamine, chondroitin is a potent anti-inflammatory. The two together even have been shown to lower cardiac risk factors..

Anti Spam Are there any side effects of glucosamine and chondroitin?. Do glucosamine and chondroitin supplements cause any adverse reactions?. Is there anything unpleasant about taking this supplement?. I have been looking into these questions for the past 3 years or so. Thats how long Ive been taking glucosamine and chondroitin for my formerly-aching knees.. Recently I updated my research on the subject, and I am very glad to be able to say that expert studies are still finding no serious side effects from taking glucosamine and chondroitin..

Clinical experience likewise suggests that some dogs and cats may appreciably benefit from chondroitin administration and others not at all. It is difficult to anticipate which animals are most likely to respond. Given the potential for benefit and the extremely low risk of any adverse side effects, chondroitin supplementation is always recommended for animals with joint pain. Where a benefit is seen, doses of more expensive and potentially deleterious drugs may be reduced, including the NSAIDs (non steroidal anti-inflammatory drugs) such as aspirin, carprofen and meloxicam. Because chondroitin protects mucosal barriers, it may not only enhance pain relief in animals administered NSAIDS, but help protect their intestinal tracts from ulcerations which are occasionally seen as a side effect of NSAID use.. Research in laboratory animals suggests that chondroitin dissolved in water before administration is more effective than when administered within a capsule.. ...
