The enzymatic degradation of starch has a myriad industrial applications. However, the branched nature of the polysaccharides that compose it poses problems, as branches have to be accommodated within an active centre best suited to linear polysaccharides. Alpha-amylases are glycoside hydrolases that break the α-1,4 bonds in starch and related glycans. The present work provides a rare insight into branch-point acceptance in these industrial catalysts.
