Characteristics of the protein coding sequence
Branching Enzyme 2
EN
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).
