NUCLEIC ACID MOLECULES CODING FOR A DEXTRAN-SACCHARASE CATALYSING THE SYNTHESIS OF DEXTRAN WITH ALPHA 1,2-OSIDIC SIDECHAINS

摘要

The invention relates to an isolated polypeptide with an glycosyl transferase enzymatic activity for producing dextrans with α(1→2) sidechains, comprising at least one region for bonding to glucan and a catalytically active region situated beyond the region bonding to glucan. The invention further relates to polynucleotides coding for said enzymes and vectors containing the same.
