Isoamylases (ISOAs) are starch debranching enzymes, including ISOA1, ISOA2 and ISOA3. ISOA1-2 are known to form a large complex and being involved in the biosynthesis and crystallization of starch. ISOA3 is involved in starch catabolism and removes different branches than ISA1-ISA2, namely short chains that prevent amylopectin crystallization [2]. This is the C-terminal beta-sandwich domain from ISOA1-3. In ISOA1, this domain is involved in dimerisation of homodimers and suggests a similar interaction to form ISOA1-ISOA2 heterodimers [1].

A, B	PF02922	Carbohydrate-binding module 48 (Isoamylase N-terminal domain) (CBM_48)	Carbohydrate-binding module 48 (Isoamylase N-terminal domain)	This domain is found in a range of enzymes that act on branched substrates - isoamylase, pullulanase and branching enzyme. This family also contains the beta subunit of 5' AMP activated kinase.	Domain

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.
