The influence of different parameters on the activity of the β-1,4-galactosyltransferase (β-1,4-GalT) from bovine milk has been investigated using various acceptor and donor substrates. It was found that the “specifier” protein α-lactalbumin (

Screening of culture collection afforded nitrile-utilizing fungi belonging to genera Aspergillus, Talaromyces and Penicillium. Fusarium solani O1 was enriched from soil using 3-cyanopyridine as the sole source of nitrogen. This strain, and Penicilliu

The regioselectivity of 20 extracellular β- N -acetylhexosaminidases of fungal origin was screened in the reverse hydrolysis with 2-acetamido-2-deoxy- d -glucopyranose. Most of the enzymes used yielded 2-acetamido-2-deoxy-β- d -glucopyranosyl-(1→

A large panel of fungal β- N -acetylhexosaminidases was tested for the regioselectivity of the β-GlcNAc transfer onto galacto -type acceptors ( d -galactose, lactose, 2-acetamido-2-deoxy- d -galactopyranose). A unique, non-reducing disaccharide β-

A careful choice of the reaction conditions (solvent, enzyme, acylating agent) allowed an efficient regioselective acylation of N-acetylhexosamines. 6-O-Acyl derivatives of 2-acetamido-2-deoxy- d -glucopyranose (GlcNAc), 2-acetamido-2-deoxy- d -galac

About 60 fungal strains were tested for production of extracellular β- N -acetylhexosaminidases. A unique β- N -acetylhexosaminidase with the β-GalNAc-ase/β-GlcNAc-ase ratio of 2.3–2.8 was found in the culture filtrates of some strains of Penic

A screening of 16 different fungal strains was performed under different cultivation conditions, using L-rhamnose or L-rhamnose-containing flavonoid glycosides (rutin, hesperidin, and naringin) as specific inducers. No significant constitutive produc

4-Nitrophenyl alpha-D-galactopyranosyl-(1-->3)-6-O-acetyl-alpha-D-galactopyranoside was prepared in a transglycosylation reaction catalyzed by alpha-D-galactosidase from Talaromyces flavus using 4-nitrophenyl alpha-D-galactopyranoside as a glycosyl d
