Phosphorylation of oligosaccharides of the lysosomal enzyme arylsulphatase A (ASA), which accumulate in the secretions of cells that mis-sort most of the newly synthesized lysosomal enzymes due to a deficiency of mannose 6-phosphate receptors, was found to be site specific. ASA residing within the secretory route of these cells contains about one third of the incorporated [2-3H]mannose in phosphorylated oligosaccharides. Oligosaccharides carrying two phosphate groups are almost 2-fold less frequent than those with one phosphate group and only a few of the phosphate groups are uncovered. Addition of a KDEL (Lys-Asp-Glu-Leu) retention signal prolongs the residence time of ASA within the secretory route 6-fold, but does not result in more efficient phosphorylation. In contrast, more than 90% of the [2-3H]mannose incorporated into secreted ASA (with or without a KDEL retention signal) is present in phosphorylated oligosaccharides. Those with two phosphate groups are almost twice as frequent as those ...

AlgE1, AlgE5 and AlgE6 are members of a family of mannuronan C-5 epimerases encoded by the bacterium Azotobacter vinelandii, and are active in the biosynthesis of alginate, where they catalyse the post-polymerization conversion of β-D-mannuronic acid (M) residues into α-L-guluronic acid residues (G). All enzymes show preference for introducing G-residues neighbouring a pre-existing G. They also have the capacity to convert single M residues flanked by G, thus condensing G-blocks to form almost homopolymeric guluronan. Analysis of the length and distribution of G-blocks based on specific enzyme degradation combined with size-exclusion chromatography, electrospray ionization MS, HPAEC-PAD (high-performance anion-exchange chromatography and pulsed amperometric detection), MALDI (matrix-assisted laser-desorption ionization)-MS and NMR revealed large differences in block length and distribution generated by AlgE1 and AlgE6, probably reflecting their different degree of processivity. When acting ...

The development of lymphoid organs depends on cross talk between hematopoietic cells and mesenchymal stromal cells and on vascularization of the lymphoid primordia. These processes are orchestrated by cytokines, chemokines, and angiogenic factors that require tight spatiotemporal regulation. Heparan sulfate (HS) proteoglycans are molecules designed to specifically bind and regulate the bioactivity of soluble protein ligands. Their binding capacity and specificity are controlled by modification of the HS side chain by HS-modifying enzymes. Although HS proteoglycans have been implicated in the morphogenesis of several organ systems, their role in controlling lymphoid organ development has thus far remained unexplored. In this study, we report that modification of HS by the HS-modifying enzyme glucuronyl C5-epimerase (Glce), which controls HS chain flexibility, is required for proper lymphoid organ development. Glce(-/-) mice show a strongly reduced size of the fetal spleen as well as a spectrum of ...

Alginate is a family of industrially important polysaccharides composed of irregular sequences of 1-4 linked β-D-mannuronic acid (M) and α-L-guluronic acid (G). They are widely used industrially as iscosifiers and gelling agents. Medical applications include utilization as dental impression materials, wound dressings and as an encapsulation matrix for cell transplants in the treatment of various diseases. Some alginates are immunogenic or have anti-tumor activity.. Commercial alginates are extracted from brown seaweeds, but the polymer is also produced by members of the bacterial genera Pseudomonas and Azotobacter. Probably in all species the alginate is first synthesized as polymannuronic acid, and then the guluronic acid moieties are introduced at the postpolymerization level by the action of mannuronan C-5- epimerases. Azotobacter vinelandii encodes a family of 7 secreted, Ca2+ -dependent mannuronan C-5-epimerases, AlgE1-7, which are composed of varying numbers of two types of structural ...
GNE myopathy, previously known as Hereditary Inclusion Body Myopathy (HIBM), or Nonaka Myopathy, is an autosomal recessive myopathy with onset in early adulthood characterized by progressive muscle atrophy and weakness. The causative gene, GNE, encodes for the bifunctional enzyme UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) that catalyzes the rate-limiting step in the biosynthesis of sialic acid (Neu5Ac). The subsequent impairment of Neu5Ac production is presumed to cause decreased sialylation of GNE myopathy muscle glycoproteins, resulting in muscle deterioration. In this protocol, we will clinically evaluate patients with GNE myopathy. To date, the amount of prospectively collected and published natural history data on GNE myopathy has been minimal due to the rare nature of this disease. This natural history study seeks to further characterize the phenotype, progression and complications of the disease. Additionally, the study is designed to identify endpoints and ...
GNE myopathy, also known as Hereditary Inclusion Body Myopathy (HIBM) is an autosomal recessive myopathy with onset in early adulthood characterized by progressive muscle weakness. The causative gene, GNE, codes for the bifunctional enzyme UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) that catalyzes the first two steps in the biosynthesis of sialic acid (SA). The subsequent paucity of SA production is presumed to cause decreased sialylation of GNE myopathy muscle glycoproteins, resulting in muscle deterioration. To date, the amount of prospectively collected and published natural history data on GNE myopathy has been minimal due to the rare nature of this disease. This natural history study seeks to further characterize the rate of progression of the disease and how it relates to age of onset. Additionally, the study is designed to elucidate functional outcome measures (endpoints) for future therapeutic trials, and correlate serum biomarkers and muscle magnetic resonance ...
In enzymology, a xylose isomerase (EC 5.3.1.5) is an enzyme that catalyzes the interconversion of D-xylose and D-xylulose. This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting aldoses and ketoses. The isomerase has now been observed in nearly a hundred species of bacteria. Xylose-isomerases are also commonly called fructose-isomerases due to their ability to interconvert glucose and fructose. The systematic name of this enzyme class is D-xylose aldose-ketose-isomerase. Other names in common use include D-xylose isomerase, D-xylose ketoisomerase, and D-xylose ketol-isomerase. The activity of D-xylose isomerase was first observed by Mitsuhashi and Lampen in 1953 in the bacterium Lactobacillus pentosus. Artificial production through transformed E.coli have also been successful. In 1957, the D-xylose isomerase activity on D-glucose conversion to D-fructose was noted by Kooi and Marshall. It is now known that isomerases have broad ...
Component of a complex that catalyzes the oxidation of glycolate to glyoxylate (PubMed:4557653, PubMed:8606183). Is required for E.coli to grow on glycolate as a sole source of carbon (PubMed:8606183). Is also able to oxidize D-lactate ((R)-lactate) with a similar rate (PubMed:4557653). Does not link directly to O(2), and 2,6-dichloroindophenol (DCIP) and phenazine methosulfate (PMS) can act as artificial electron acceptors in vitro, but the physiological molecule that functions as primary electron acceptor during glycolate oxidation is unknown (PubMed:4557653).
Heparan sulfate (HS) and heparin are linear polysaccharide chains covalently O-linked to serine residues within the core proteins, so called HS proteoglycans (PGs) or heparin PG. HSPGs are produced by almost all mammalian cells and known to play important roles in developmental processes, physiological and pathological conditions; whereas heparin PG is produced by mast cells and best known as an anticoagulant in clinic.Biosynthesis of HS/heparin occurs in Golgi compartment and involves many enzymes, one of which is glucuronyl C5-epimerase (Hsepi) that catalyzes the conversion of D-glucuronic acid (GlcA) to L-iduronic acid (IdoA). Heparanase is an enzyme involved in metabolism of HS; it cleaves the linkage between GlcA and glucosamine residues in HS/heparin chains. Heparanase is expressed essentially by all cells and found up-regulated in many metastatic tumors.This thesis focuses on the structure and functions of HS/heparin through studies on the implications of Hsepi and heparanase. My study ...
We have generated two transgenic mice strains (one is overexpressing the mutated key enzyme of the sialic acid biosynthesis, which leads to high sialic acid levels and one has a defect in the sialic acid biosynthesis). Both strains will be compared with wild-type animals. We plan to analyse O-GlcNAc, sialic acid, sialic acid binding proteins and sialic acid-dependent differentiation markers in all organs over the whole lifespan and quantify age-dependent muscle performance in vivo. The outcome of metabolic sialic acid engineering will be analysed in embryonic stem cells (differentiation) and neuronal cells (neurite outgrowth e.g. regeneration). We also plan to analyse the involvement of sialylation and O-GlcNAcylation on the function of endothelial cells. After metabolic engineering we will analyse their barrier capacity and age-related impact on neuronal cells by real-time cell analysis. Since high levels of glucose induce glycation of proteins, we will analyse the function of an artificial ...

Striving to create factories measuring several dozen mm wide and several mm deep. When we can see things which we have never been able to see before, and create things we have never been able to create before, cell-in-micro-factories will integrate these optical manufacturing technologies. These factories, smaller by far than anything that has come before, are Professor Takahashis own original idea. The smallest factories which exist today are "desktop micro-factories," which consist of machine tools such as micro-lathes. Cell-in-micro-factories, measuring just several dozen millimeters wide by several millimeters deep, are to contain the most advanced optical technologies, performing everything from measurement, processing, and handling to conveyance and defect detection. The objects they manufacture will measure less than 1 millimeter. When asked where his creativity springs from, Professor Takahashi answers, "I come from Kansai, so I love comedy. Comedy consists of gaps, right? I think ...

Saccharomyces cerevisiae strains expressing D-xylose isomerase (XI) produce some of the highest reported ethanol yields from D-xylose. Unfortunately, most bacterial XIs that have been expressed in S. cerevisiae are either not functional, require additional strain modification, or have low affinity for D-xylose. This study analyzed several XIs from rumen and intestinal microorganisms to identify enzymes with improved properties for engineering S. cerevisiae for D-xylose fermentation. Four XIs originating from rumen and intestinal bacteria were isolated and expressed in a S. cerevisiae CEN.PK2-1C parental strain primed for D-xylose metabolism by over expression of its native D-xylulokinase. Three of the XIs were functional in S. cerevisiae, based on the strains ability to grow in D-xylose medium. The most promising strain, expressing the XI mined from Prevotella ruminicola TC2-24, was further adapted for aerobic and fermentative growth by serial transfers of D-xylose cultures under aerobic, and followed

In order for an accidentally generated string of letters to convey a meaningful message, it needs to satisfy three very stringent conditions, each more difficult than the last: first, the letters need to be arranged into meaningful words; second, the sequence of words has to conform to the rules of syntax; and finally, the sequence of words has to make sense at the semantic level: in other words, it needs to express a meaningful proposition. For a string of letters generated at random to meet all of these conditions would indeed be fantastically improbable. But heres the thing: living things dont need to satisfy any of these conditions. Yes, it is true that all living things possess a genetic code. But it is quite impossible for this code to generate anything like nonsense words like "sdfuiop", and additionally, there is nothing in the genome which is remotely comparable to the rules of syntax, let alone the semantics of a meaningful proposition. The sequence of amino acids in a protein needs ...
