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	PF11852	Alpha-1,6-glucosidases, pullulanase-type, C-terminal (Pullul_strch_C)	Alpha-1,6-glucosidases, pullulanase-type, C-terminal	-	Family
A	PF17967	Pullulanase N2 domain (Pullulanase_N2)	Pullulanase N2 domain	This domain is found close to the N-terminus of the Klebsiella starch debranching pullulanase enzyme [1]. The structure of the domain is a beta sandwich fold.	Domain
