Abstract

DEXTRANSUCRASE is a representative member of the general class of enzymes known as transglycosidases. In this particular example, the glucosyl group from sucrose is transferred to a suitable acceptor, which causes chain initiation, and dextran is formed. Polymer-formation is governed by many factors such as the nature of the acceptor molecule, pH and temperature1.
