(in: Bacteria). Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 3.2Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function CDAS_BACSP Hydrolyzes alpha-, beta- and gamma-cyclodextrins and the resulting linear maltodextrins, with the highest activity with beta-cyclodextrin (cyclomaltoheptaose). Soluble starch is hydrolyzed slowly, but it is nevertheless preferred over pullulan as a substrate. Is able to hydrolyze amylose and amylopectin, with a very strong preference for amylose, with maltose and glucose as the main products (PubMed:9606956, PubMed:10620329, PubMed:16536613). Maltose and glucose are the main hydrolysis products of cyclomaltodextrins, maltodextrins and starch, whereas panose is the main hydrolysis product of pullulan. Acarbose is partially hydrolyzed to glucose and pseudotrisaccharide. No activity with maltose as substrate (PubMed:9606956, PubMed:10620329). Has transglycosylating activity with high concentrations of maltotriose, maltotetraose and starch (PubMed:9606956). Evolutionary Conservation Check, as determined by ConSurfDB.
