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.	Domain
A	PF11941	Domain of unknown function (DUF3459) (DUF3459)	Domain of unknown function (DUF3459)	This presumed domain is functionally uncharacterised. This domain is found in bacteria. This domain is about 110 amino acids in length. This domain is found associated with Pfam:PF00128, Pfam:PF02922.	Domain
