Description
| - A high-yield preparatory procedure for the synthesis of p-nitrophenyl 2-acetamido-2-deoxy-b-dgalacto-hexodialdo-1,5-pyranoside (2) using the galactose oxidase from Dactylium dendroides in a batch reactor was developed. Enzymatic recognition of this aldehyde and the respective uronic acid 3 obtained by NaClO2 oxidation was studied using a set of 36 fungal b-N-acetylhexosaminidases from Acremonium, Aspergillus, Penicillium and Talaromyces genera. The aldehyde 2 was readily hydrolysed by all tested b-Nacetylhexosaminidases but neither the uronic acid 3 nor its methyl ester 4 were accepted. Molecular modelling with docking into the active centre of the b-Nacetylhexosaminidase from Aspergillus oryzae revealed that the aldehyde 2 is processed as a C-6 geminal diol by the enzyme

- Byla vyvinuta vysoce účinná metoda pro syntézu 2-acetamido-2-deoxy-b-D-galakto-hexodialdo-1,5-pyranosidu (látka 2) s použitím galaktosaoxidasy z Dactylium dendroides a vsádkového reaktoru. Enzymatické rozpoznání tohoto aldehydu a též odpovídající kyseliny uronové (látka 3) získané oxidací NaClO2 bylo studováno na souboru 36 plísňových beta-N-acetylhexosaminidas z druhů Acremonium, Penicillium a Talaromyces. Aldehyd 2 byl snadno hydrolyzován všemi testovanými enzymy, ale ani kyselina uronová 3 ani její methyl ester nebyly akceptovány. Molekulární modelování do struktury aktivního centra hexosaminidasy z Aspergillus oryzae odhalilo, že aldehyd 2 je pravděpodobně enzymem zpracováván ve formě C-6 geminálního diolu (cs)
