Glycogen branching enzymes and carbohydrates modified thereby

摘要

There are provided novel cDNA polynucleotide sequences obtained from Aureobasidium pullulans which encode novel carbohydrate modifying enzymes. Host cells and in particular transgenic plants transfected with recombinant genetic constructs comprising the novel cDNA sequences are described. The enzymes encoded by the cDNA polynucleotide sequences may be used to produce carbohydrates or to modify existing carbohydrates, and this may be achieved in vitro or in vivo (for example by a transgenic plant). The modified carbohydrates so produced form a further apsect of the invention.
