Characteristics of the protein coding sequence
Name of the protein expressed by the coding sequence
Branching Enzyme 1
Biological function
The be1 and be2 genes code for starch branching enzymes which catalyse the splitting of alpha-1,4-glucans and the subsequent formation of alpha-1,6-glycosidic bonds between glucan chains during amylopectin synthesis.
The isozymes BE1 and BE2 differ with regard to their amino acid sequences, their expression patter (BE1 is expressed mainly in potato tubers, BE2 mainly in leaves) and their specificity (e.g. size of the transferred carbohydrate chains).
Related trait(s) or use(s) in biotechnology
  • altered carbohydrate composition: increased amylopectin content
