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.

PF20756Alpha-amylase SusG, CBM58 domain (SusG_CBM58)Alpha-amylase SusG, CBM58 domainEnzymes of the Glycoside hydrolase family 13 typically show three domains A, B and C.

In addition to these, Alpha-amylase SusG from Bacteroides thetaiotaomicron (Swiss:Q8A1G3) includes the insertion of a unique carbohydrate binding module (CBM) family 58 (this entry), which gives the protein an elongated shape. SusG, located on the outer membrane of the cell, cleaves starch into oligosaccharides before internalisation for degradation. CBM58 is approximately 120 residues in length. This domain folds into a beta sandwich and adopts an immunoglobulin-like topology with a flat five-stranded antiparallel beta sheet opposing a four-stranded antiparallel beta sheet which features three protruding loops. Y260, W287, and W299 form the starch-binding site [1, 2, 3].
