The Protein Data Bank (PDB) is celebrating its twenty-year anniversary of “Molecule of the Month”. Here we present the winner of June 2011, the glucansucrase protein. PDB has written a very interesting outline of these glucansucrase enzymes that are crucial to the CarbExplore technologies for oligosaccharide and polysaccharide synthesis, and for glucosylation of diverse acceptor substrates.
