    Synthesis of α-Gal epitope derivatives with a galactosyltransferase–epimerase fusion enzyme
    摘要:
    beta -Gal epitopes are carbohydrate structures bearing an alpha -D-Galp-(1 --> 3)-beta -D-Galp terminus and are the main cause of antibody-mediated hyperacute rejection in xenotransplantation. Nine monosaccharides and ten disaccharides were evaluated as substrates for a fusion protein, which contains both alpha-(1 --> 3)-galactosyltransferase and uridine-5'-diphosphogalactose 4-epimerase. Four disaccharide and six trisaccharide alpha -Gal epitope derivatives were synthesized utilizing this novel fusion enzyme. (C) 2000 Elsevier Science Ltd. All rights reserved.

  • A simple strategy for changing the regioselectivity of glycosidase-catalysed formation of disaccharides
    作者:Kurt G.I. Nilsson
    DOI:10.1016/0008-6215(87)80271-9
    日期:1987.9
    The regioselectivity of glycosidase-catalysed formation of disaccharides can be changed by using alpha- or beta-glycosyl acceptors with various aglycons. The preponderant formation of other than (1----6) linkages can be effected with glycosidases which normally give (1----6) linkages. Thus, an alpha-D-galactosidase can be induced to catalyse the formation mainly of alpha-(1----2)-, alpha-(1----3),
    通过使用带有各种糖苷配基的α-或β-糖基受体可以改变糖苷酶催化的二糖形成的区域选择性。除了(1 ---- 6)键以外,优势糖的形成可以通过通常具有(1 ---- 6)键的糖苷酶来实现。因此,可以诱导α-D-半乳糖苷酶主要催化α-(1 ---- 2)-,α-(1 ---- 3)或α-(1 ---- 6)的形成。 )连接的半乳​​糖苷。糖苷配基的结构和糖苷键的构型均可对二糖形成的区域选择性产生显着影响。描述了α-D-Galp-(1 ---- 3)-α-D-Galp-OMe,β-D-Galp-(1 ---- 3)的酶促合成,产率为20-30% β-D-Galp-OMe,β-D-Galp-(1 ---- 6)-α-D-Galp-OMe,α-D-Manp-(1 ---- 2)-alpha- D-Manp-OMe,alpha-D-Manp-(1 ---- 6)-alpha-D-Manp-OMe,alpha-D-Galp-(1
  • Glycosidase-catalysed synthesis of α-galactosyl epitopes important in xenotransplantation and toxin binding using the α-galactosidase from Penicillium multicolor

    日期:——
    The α-galactosidase from Penicillium multicolor catalyses highly regioselective galactosyl transfer on to mono- and di-saccharide acceptors that have a non-reducing terminal galactose unit to give products containing the α-D-Galp-(1→3)-D-Galp epitope found on pig tissue and which is responsible for the hyperacute rejection response in xenotransplantation of pig organs into man.

  • A method of controlling the regioselectivity of glycosidic bonds
    申请人:Svenska Sockerfabriks AB
    公开号:EP0226563A1
    公开(公告)日:1987-06-24
    A method of controlling the regioselectivity of the glycosidic bond between glycosyl donor and glycosyl acceptor in the enzymatic production of an oligosaccharide compound which either consists of or is a fragment or an analog of the carbohydrate part in a glycoconjugate, by reverse hydrolysis or transglycosidation reactions, is described. The syn­thesis is carried out in that a donor substance which is a mono- or oligosaccharide or a glycoside thereof, is caused to react, in the presence of a glycosidase, with an acceptor substance which is an O-, N-, C- ­or S-glycoside consisting of a monosaccharide, oligo­saccharide or a saccharide analog and at least one aglycon which is O-, N-, C- or S-glycosidically bonded in 1-position, the α- or β-configuration being selected on the glycoside bond between the glycosyl group and the aglycon in the acceptor substance, and the oligo­saccharide compound being separated from the reaction mixture.
