A	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.	Domain
A	PF18033	SpuA C-terminal (SpuA_C)	SpuA C-terminal	This is the C-terminal beta sandwich domain found in Streptococcus pneumoniae Spu4 proteins. Spu4 is a large multimodular cell wall-attached enzyme involved in the degradation of glycogen [1].	Domain
