A 4-fold purification has been reached with a 1.3 % recovery. The subunit molecular weight of adenosine nucleosidase was determined by mass spectrometry to be 26,103 daltons. The number of subunits was 1. The Michaelis constant, Km, and the maximum velocity, V max, for adenosine were determined to be 137 ± 48 µM, and 0.34 ± 0.02 µM/min respectively. -

Abstract: Fucose sugars are expressed on mammalian cell L-Fucose (Fuc) is a 6-deoxyhexose expressed at the termini of glycan membranes as part of glycoconjugates and mediates essential chains that decorate cell surface proteins and lipids.1 The fucose physiological processes. The aberrant expression of fucosylated residues on glycoconjugates are essential mediators of physiological glycans has been linked to pathologies such as cancer, inflammation, processes. For example, the fucose moiety in the tetrasaccharide infection, and genetic disorders. Tools to modulate fucose expression sialyl Lewisx (sLex) expressed on leukocytes is recognized by selectin on living cells are needed to elucidate the biological role of fucose receptors that regulate leukocyte recruitment and extravasation. -
An Atpase Domain Common to Prokaryotic Cell Cycle Proteins
Proc. Natl. Acad. Sci. USA Vol. 89, pp. 7290-7294, August 1992 Biochemistry An ATPase domain common to prokaryotic cell cycle proteins, sugar kinases, actin, and hsp7O heat shock proteins (structural comparison/property pattern/remote homology) PEER BORK, CHRIS SANDER, AND ALFONSO VALENCIA European Molecular Biology Laboratory, D-6900 Heidelberg, Federal Republic of Germany Communicated by Russell F. Doolittle, March 6, 1992 ABSTRACT The functionally diverse actin, hexokinase, and hsp7O protein families have in common an ATPase domain of known three-dimensional structure. Optimal superposition ofthe three structures and alignment ofmany sequences in each of the three families has revealed a set of common conserved residues, distributed in five sequence motifs, which are in- volved in ATP binding and in a putative interdomain hinge. From the multiple sequence aliment in these motifs a pattern of amino acid properties required at each position is defined. The discriminatory power of the pattern is in part due to the use of several known three-dimensional structures and many sequences and in part to the "property" method ofgeneralizing from observed amino acid frequencies to amino acid fitness at each sequence position. A sequence data base search with the pattern significantly matches sugar kinases, such as fuco-, glucono-, xylulo-, ribulo-, and glycerokinase, as well as the prokaryotic cell cycle proteins MreB, FtsA, and StbA. These are predicted to have subdomains with the same tertiary structure as the ATPase subdomains Ia and Ha of hexokinase, actin, and Hsc7O, a very similar ATP binding pocket, and the capacity for interdomain hinge motion accompanying func- tional state changes. -

Native Microorganisms Nucleoside Phosphorylase Cat
Native Microorganisms Nucleoside Phosphorylase Cat. No. NATE-0606 Lot. No. (See product label) Introduction Description In enzymology, a purine-nucleoside phosphorylase (EC 2.4.2.1) is an enzyme that catalyzes the chemical reaction:purine nucleoside + phosphate↔ purine + alpha-D-ribose 1-phosphate. Thus, the two substrates of this enzyme are purine nucleoside and phosphate, whereas its two products are purine and alpha-D-ribose 1-phosphate. This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. This enzyme participates in 3 metabolic pathways:purine metabolism, pyrimidine metabolism, and nicotinate and nicotinamide metabolism. Applications Nucleoside phosphorylase is used in coupled enzyme systems to measure protein dephosphorylation. This enzyme is useful for enzymatic determination of inorganic phosphorus, 5′-nucleotidase and adenosine deaminase when coupled with xanthine oxidase (XTO-212) and uricase (UAO-201, UAO-211). Purine nucleoside phosophorylase has shown the ability to perform both phosphorylosis and synthesis of purine deoxy-and ribonucleosides. It has also been found that membrane-ass ociated nucleoside phosphorylases may have a transmembranal orientation with their base and ribose-1-P binding sites on opposite sides of the membrane. Synonyms purine-nucleoside phosphorylase; inosine phosphorylase; PNP; PNPase; PUNPI; PUNPII; inosine-guanosine phosphorylase; nucleotide phosphatase; purine deoxynucleoside phosphorylase; purine deoxyribonucleoside phosphorylase; purine nucleoside phosphorylase; -

Effects of Glycosylation on the Enzymatic Activity and Mechanisms of Proteases
International Journal of Molecular Sciences Review Effects of Glycosylation on the Enzymatic Activity and Mechanisms of Proteases Peter Goettig Structural Biology Group, Faculty of Molecular Biology, University of Salzburg, Billrothstrasse 11, 5020 Salzburg, Austria; [email protected]; Tel.: +43-662-8044-7283; Fax: +43-662-8044-7209 Academic Editor: Cheorl-Ho Kim Received: 30 July 2016; Accepted: 10 November 2016; Published: 25 November 2016 Abstract: Posttranslational modifications are an important feature of most proteases in higher organisms, such as the conversion of inactive zymogens into active proteases. To date, little information is available on the role of glycosylation and functional implications for secreted proteases. Besides a stabilizing effect and protection against proteolysis, several proteases show a significant influence of glycosylation on the catalytic activity. Glycans can alter the substrate recognition, the specificity and binding affinity, as well as the turnover rates. However, there is currently no known general pattern, since glycosylation can have both stimulating and inhibiting effects on activity. Thus, a comparative analysis of individual cases with sufficient enzyme kinetic and structural data is a first approach to describe mechanistic principles that govern the effects of glycosylation on the function of proteases. The understanding of glycan functions becomes highly significant in proteomic and glycomic studies, which demonstrated that cancer-associated proteases, such as kallikrein-related peptidase 3, exhibit strongly altered glycosylation patterns in pathological cases. Such findings can contribute to a variety of future biomedical applications. Keywords: secreted protease; sequon; N-glycosylation; O-glycosylation; core glycan; enzyme kinetics; substrate recognition; flexible loops; Michaelis constant; turnover number 1. -
Towards Therapy for Batten Disease
Towards therapy for Batten disease Mariana Catanho da Silva Vieira MRC Laboratory for Molecular Cell Biology University College London PhD Supervisor: Dr Sara E Mole A thesis submitted for the degree of Doctor of Philosophy University College London September 2014 Declaration I, Mariana Catanho da Silva Vieira, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract The gene underlying the classic neurodegenerative lysosomal storage disorder (LSD) juvenile neuronal ceroid lipofuscinosis (JNCL) in humans, CLN3, encodes a polytopic membrane spanning protein of unknown function. Several studies using simpler models have been performed in order to further understand this protein and its pathological mechanism. Schizosaccharomyces pombe provides an ideal model organism for the study of CLN3 function, due to its simplicity, genetic tractability and the presence of a single orthologue of CLN3 (Btn1p), which exhibits a functional profile comparable to its human counterpart. In this study, this model was used to explore the effect of different mutations in btn1 as well as phenotypes arising from complete deletion of the gene. Different btn1 mutations have different effects on the protein function, underlining different phenotypes and affecting the levels of expression of Btn1p. So far, there is no cure for JNCL and therefore it is of great importance to identify novel lead compounds that can be developed for disease therapy. To identify these compounds, a drug screen with btn1Δ cells based on their sensitivity to cyclosporine A, was developed. Positive hits from the screen were validated and tested for their ability to rescue other specific phenotypes also associated with the loss of btn1. -
