4V3B: The Structure Of Alpha2,3-sialyltransferase Variant 1 From Pasteurella Dagmatis In Complex With The Donor Product Cmp

Citation:
Abstract
Structure-guided active-site redesign of a family GT-80 beta-D-galactoside sialyltransferase (from Pasteurella dagmatis) to change enzyme regioselectivity from alpha-2,3 in the wild type to alpha-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.
