Carbohydrate binding sites in a pancreatic α‐amylase‐substrate complex, derived from X‐ray structure analysis at 2.1 Å resolution

The X‐ray structure analysis of a crystal of pig pancreatic α‐amylase (PPA, EC 3.2.1.1.) that was soaked with the substrate maltopentaose showed electron density corresponding to two independent carbohydrate recognition sites on the surface of the molecule. Both binding sites are distinct from the a...
