  A spacer-modified disaccharide as a photoaffinity reagent for the acceptor-binding area of bovine (1 → 4)-β-d-galactosyltransferase: comparison of its acceptor properties with those of other 2-acetamido-2-deoxy-β-d-glucopyranosides

  摘要：

  The spacer-modified disaccharide 1,10-di-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-azi-1,10-decanediol (10) that mimics the biantennary. core heptasaccharide of N-glycoproteins has been synthesised. Compound 10 is an excellent acceptor in galactosyltransferase-catalysed galactosylation by UDP-galactose, is superior (7-8-fold) to analogues that have only one GlcNAc unit, and is an efficient photoaffinity reagent for galactosyltransferase. In the presence of UDP-Gal. no photoaffinity labelling by 10 takes place, which agrees the mechanism of galactosyltransferase action.

  The biantennary spacer-modified trisaccharide glycoside methyl 3,6-di-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyloxyethyl)-alpha-D-mannopyranoside (5) was synthesised and used together with several 2-acylamino-2-deoxy-D-glucose derivatives in competition experiments with beta-D-galactosyltransferase. CoMpound 5 was an acceptor substrate (K(M) 0.18 mM) comparable to the biantennary core heptasaccharide of glycoproteins (K(M) 0.13 mM). Replacing the N-acetyl group by other N-acyl groups did not alter the kinetic parameters significantly. When the N-acyl group was iodoacetyl, the compound was an irreversible inhibitor,
