Chains	Enzyme Name	Description	Catalytic Residues
A	oligo-1,6-glucosidase M-CSA #285	Oligo-1,6-glucosidase (dextrin 6-alpha-D-glucanohydrolase) hydrolyses the non-reducing terminal alpha-1,6-glucosidic bonds of isomaltosaccharides, panose, and alpha-limit dextrins, but fails to act on alpha,1,4-glucosidic bonds of maltosaccharides [PMID:8370659]. The anomeric configuration of the substrate is retained, thus the mechanism proceeds via a double displacement process [PMID:9193006, PMID:10331869]. In addition, this enzyme belongs to the family 13 of glycosyl hydrolases, also known as the alpha-amylase family.
