    Carbohydrate-binding domains are usually small and physically separate from the catalytic domains of hydrolytic enzymes. Glucoamylase 1 (G1) from Aspergillus niger, an enzyme used widely in the food and brewing industries, contains a granular starch binding domain (SBD) which is separated from the catalytic domain by a semi-rigid linker. The aim of this study was to determine how the SBD binds to starch, and thereby more generally to throw light on the role of carbohydrate-binding domains in the hydrolysis of insoluble polysaccharides.
