  • Novel substrate specificities of two lacto-N-biosidases towards β-linked galacto-N-biose-containing oligosaccharides of globo H, Gb5, and GA1

    We describe the novel substrate specificities of two independently evolved lacto-N-biosidases (LnbX and LnbB) towards the sugar chains of globo-and ganglio-series glycosphingolipids. LnbX, a non-classified member of the glycoside hydrolase family, isolated from Bifidobacterium longum subsp. longum, was shown to liberate galacto-N-biose (GNB: Gal beta 1-3GalNAc) and 2'-fucosyl GNB (a type-4 trisaccharide) from Gb5 pentasaccharide and globo H hexasaccharide, respectively. LnbB, a member of the glycoside hydrolase family 20 isolated from Bifidobacterium bifidum, was shown to release GNB from Gb5 and GA1 oligosaccharides. This is the first report describing enzymatic release of beta-linked GNB from natural substrates. These unique activities may play a role in modulating the microbial composition in the gut ecosystem, and may serve as new tools for elucidating the functions of sugar chains of glycosphingolipids.

    The invention relates to carbohydrate ligands and moieties, respectively, mimicking glycoepitopes comprised by glycosphingolipids of the nervous system, particularly glycoepitopes comprised by glycosphingolipids of the cerebroside, the globoside-, the ganglioside- and the sulfoglucuronyl paragloboside type, which are bound by anti-glycan antibodies associated with neurological diseases. The invention further relates to the use of these carbohydrate ligands/moieties, in diagnosis as well as for the treatment of neurological diseases associated with anti-glycan antibodies. In particular, the invention relates to compounds of formula (I) and (II) and to therapeutically acceptable polymers comprising a multitude of these compounds, including polymers with loading of one compound of formula (I) or (II) or combinations of several compounds of formula (I), and/or (II). The compounds of formula (I) are defined as: formula (I), wherein RI1 is Z or (AA) or (BB) or (CC) or (DD); wherein RI2 is H, SO3H, or (EE) or (FF) or (GG) or (HH) or (JJ) or (KK) or (LL), wherein RI3 is H or (MM); wherein RI4 is H or (NN) or (OO), wherein RI5 and RI6 are independently H or (EE); wherein RI7 is H or (EE) or (FF) and compounds of formula (II) are defined as: formula (II), wherein RII1 is Z or (PP), wherein RII2 is Z or (QQ) or (RR) or (SS) or (TT), wherein Z is -N(Ra)-A-B-CH2-(CH2)q-SH, wherein Ra is H, C1-C4-alkyl, C1-C4-alkoxy, CH2C6H5, CH2CH2C6H5, OCH2C6H5, or OCH2CH2C6H5; A is C1-C7-alkylene, C1-C7-alkoxy, C1-C4-alkyl–(OCH2CH2)pO–C1-C4-alkyl, or C1-C7-alkoxy-Rb, wherein Rb is an optionally substituted aryl or an optionally substituted heteroaryl, and wherein p is 0 to 6, preferably p is 1, 2 or 3, and further preferably p is 1; B is NHC(O), S or CH2; q is 0 to 6, preferably q is 1, 2, 3 or 4, and further preferably q is 1 or 2.
