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
A	PF00128	Alpha amylase, catalytic domain (Alpha-amylase)	Alpha amylase, catalytic domain	Alpha amylase is classified as family 13 of the glycosyl hydrolases.

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
A	PF03714	Bacterial pullanase-associated domain (PUD)	Bacterial pullanase-associated domain	Domain is found in pullanase - carbohydrate de-branching - proteins. It is found both to the N or the C terminii of of the alpha-amylase active site region. This domain contains several conserved aromatic residues that are suggestive of a carbohydrat ...	Domain is found in pullanase - carbohydrate de-branching - proteins. It is found both to the N or the C terminii of of the alpha-amylase active site region. This domain contains several conserved aromatic residues that are suggestive of a carbohydrate binding function.	Domain
