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	PF22026	Alpha-amylase C-terminal domain (Alpha-amylase_C_2)	Alpha-amylase C-terminal domain	This is the C-terminal domain of alpha-amylase and related enzymes. This domain follows the catalytic beta/alpha domain. It folds into a beta-sandwich with a greek key topology.	Domain
