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 assume a beta-sandwich structure composed of the eight antiparallel beta-strands. A ten residue linker is also present at the C-terminal end, which connects the N terminal domain to a distal domain in the protein. This domain participates in oligomerisation of the protein, wherein the N-terminal domain of one subunit contacts the active centre of the other subunit, and is also required for binding of cyclodextrin to substrate [1].	Domain
A, B, C, D, E A, B, C, D, E, F	PF10438	Cyclo-malto-dextrinase C-terminal domain (Cyc-maltodext_C)	Cyclo-malto-dextrinase C-terminal domain	This domain is at the very C-terminus of cyclo-malto-dextrinase proteins and consists of 8 beta strands, is largely globular and appears to help stabilise the acitve sites created by upstream domains, Cyc-maltodext_N Pfam:PF09087, and Alpha-amylase P ...	This domain is at the very C-terminus of cyclo-malto-dextrinase proteins and consists of 8 beta strands, is largely globular and appears to help stabilise the acitve sites created by upstream domains, Cyc-maltodext_N Pfam:PF09087, and Alpha-amylase Pfam:PF00128. Cyclo-malto-dextrinases hydrolyse cyclodextrans to maltose and glucose and catalyse trans-glycosylation of oligosaccharides to the C3-, C4- or C6-hydroxyl groups of various acceptor sugar molecules.
