| Description
| - Enzym pyranózo-dehydrogenáza (EC 1.1.99.29) získaný z kultivačního media houby Agaricus meleagris katalyzoval oxydaci řady mono- a disacharidů v polohách C-1, C-2, C-3, C-1,3 nebo C-2,3, akceptorem elektronů byl 1,4-benzochinon. D-ribosa, D-allosa, D-gulosa a D-talosa byly zoxydovány na příslušné aldonové kyseliny. L-arabinosa byla přeměněna výlučně na 2-dehydro-L-arabinosu, zatímco D-xylosa podlehla konkurenčním C-2 a C-3 oxydacím, následovaným dvojnásobnou oxydací na 2,3-dehydro-D-arabinosu. Hlavními konečnými produkty oxydace maltosy a celobiosy byly nové látky 2,3-didehydromaltosa a 2,3-didehydro-celobiosa, vzniklé přes 2- a 3-monooxydované meziprodukty. V malém množství došlo i k C-1,(3)-dioxydaci na příslušné bionové kyseliny. Maltosa byla přednostně oxydována na C-3 koncové glukopyranózové jednotky a na C-1 redukující skupiny (cs)
- The fungal enzyme pyranose dehydrogenase (EC 1.1.99.29) was isolated from the culture media of Agaricus meleagris and purified to apparent homogeneity. Depending on the substrate used, it catalyzed C-1, C-2, C-3 or C-2,3 (di)oxidation of a number of mono- and disaccharides, 1,4-benzoquinone acted as an electron donor. D-Ribose, D-allose, D-gulose and D-talose were oxidized to the corresponding aldonic acids. L-Arabinose was selectively oxidized to 2-dehydro-L-arabinose (L-erythro-pentos-2-ulose), D-xylose was simultaneously oxidized to 2- and 3-dehydro derivatives and finally to 2,3-didehydro-D-xylose (D-threo-pentos-2,3-diulose). The major final oxidation products of maltose and cellobiose were novel compounds 2,3-didehydromaltose and 2,3-didehydrocellobiose (and betaalfa-D-ribo-hexopyranos-3-ulosyl-(1-4)-D-arabino-hexos-2-ulose), formed via 2 and 3 monooxidation intermediates
