Dextransucrase-catalyzed elongation of polysaccharide brushes with immobilized mono-/di-saccharides as acceptors†
Abstract
A quartz crystal microbalance (QCM) was used to monitor dextransucrase (DSase)-catalyzed polysaccharide elongation on the glucose-/maltose-ended self-assembly monolayer (SAM) surfaces. Kinetic parameters of the enzymatic elongation indicate that maltose is a promising substrate acceptor for DSase.
