An α-L-fucosidase from Penicillium multicolor as a candidate enzyme for the synthesis of α (1→3)-linked fucosyl oligosaccharides by transglycosylation

A new α-L-fucosidase was partially purified from the culture broth of Penicillium multicolor, which was available commercially as a freeze dried powder by the name of Lactase-P. This enzyme catalysed the transglycosylation of fucose residue of p-nitrophenyl-α-L-fucopyranoside to give α-L-Fuc-(1→3)-D-G1c or α-L-Fuc-(1→3)-D-GlcNAc regioselectiveiy. This enzyme was more stable in the organic co-solvents than the α-fucosidase from Aspergillus niger, which was also proposed previously by us as an enzyme to produce fucosyl oligosaccharides.

SYNTHESIS OF OLIGOSACCHARIDES OF L-FUCOSE CONTAINING α- AND β-ANOMERIC CONFIGURATIONS IN THE SAME MOLECULE

Some L-fucopyranosyl di-, tri-, and tetra-saccharides containing D-glucose and D-galactose have been synthesised.The use of mercuric cyanide and 2-O-benzyl-3,4-di-O-p-nitrobenzoyl-α-L-fucopyranosyl bromide gave α-L-fucopyranosides stereospecifically, but 2,3,4-tri-O-acetyl-α-L-fucopyranosyl bromide gave mixtures with selectivity favouring the β anomer.A tetrasaccharide was prepared containing both α- and β-L-fucopyranosyl residues in the same molecule, as part of a structure occuring in some extracellular bacterial polysaccharides.The configuration and positions of substitution of fucopyranosyl residues were clearly shown by 1H- and 13C-n.m.r. data.

Reduction of the primary alcohol group of 1,2:5,6-isopropylidene-3-O-(2,3,4-trideoxy-α-L-glycero-hex-2-enopyranosyl)-α-D-glucofuranose by p-toluenesulfonylation, substitution by iodine, and tributylstannane treatment, gave a 6'-deoxy derivative, which was
