Complete Switch from Alpha2,3- to Alpha2,6-Regioselectivity in Pasteurella Dagmatis Beta-D-Galactoside Sialyltransferase by Active-Site Redesign Chem.Commun.(Camb.), 51:3083-, 2015 Cited by PubMed Abstract: Structure-guided active-site redesign of a family GT-80 β-D-galactoside sialyltransferase (from Pasteurella dagmatis) to change enzyme regioselectivity from α-2,3 in the wild type to α-2,6 in a P7H-M117A double mutant is reported. Biochemical data for sialylation of lactose together with protein crystal structures demonstrate highly precise enzyme engineering.
