PF21156 | Isoamylase 1-3, C-terminal (ISOA1-3_C) | Isoamylase 1-3, C-terminal | 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 d ... | Domain | |
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 | |
PF00128 | Alpha amylase, catalytic domain (Alpha-amylase) | Alpha amylase, catalytic 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, a ... | Domain |
