Alpha amylase is classified as family 13 of the glycosyl hydrolases. The structure is an 8 stranded alpha/beta barrel containing the active site, interrupted by a ~70 a.a. calcium-binding domain protruding between beta strand 3 and alpha helix 3, and a carboxyl-terminal Greek key beta-barrel domain.

Members of this family, which are found in the prokaryotic protein glycosyltrehalose trehalohydrolase, assume a gamma-crystallin-type fold with a five-stranded anti-parallel beta-sheet that packs against the C-terminal side of a beta-alpha barrel. This domain is common to family 13 glycosidases and typically contains a five to ten strand beta-sheet, however its precise fold varies [1].	Domain
