Item Activity of Debaryomyces hansenii UFV-1 a-galactosidases against a-D-galactopyranoside derivatives(Carbohydrate Research, 2011-04-01) Rezende, Sebastião T. de; Viana, Pollyanna A.; Alves, Arianne de A.; Manfrini, Rozângela M.; Alves, Ricardo J.; Bemquerer, Marcelo P.; Santoro, Marcelo M.; Guimarães, Valéria M.α-d-Galactopyranosides were synthesized and their inhibitory activities toward the Debaryomyces hansenii UFV-1 extracellular and intracellular α-galactosidases were evaluated. Methyl α-d-galactopyranoside was the most potent inhibitor compared to the others tested, with values of 0.82 and 1.12 mmol L−1, for extracellular and intracellular enzymes, respectively. These results indicate that the presence of a hydroxyl group in the C-6 position of α-d-galactopyranoside derivatives is important for the recognition by D. hansenii UFV-1 α-galactosidases.
