Abstract excerpt

Besides their catalysis, specific interactions between starch/glycogen processing enzymes and their substrates have been reported. Multiple branching enzyme (BE) isoforms, BE1, BE2, and BE3, have been found in a limited number of cyanobacterial species that are characterized by amylopectin accumulation. Seven surface binding sites (SBSs) located away from the active site have been identified in crystal structures...
