Number of residues	None
Molecular Weight	55046.815
Theoretical pI	5.75
GO Classification	Functions oxidoreductase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor metal ion binding alpha-1,4-glucosidase activity maltose alpha-glucosidase activity Processes Components
General Function	Oxidoreductase activity, acting on the ch-oh group of donors, nad or nadp as acceptor
Specific Function	Alpha-glycosidase with a very broad specificity. Hydrolyzes maltose and other small maltooligosaccharides but is inactive against the polymeric substrate starch. AglA is not specific with respect to the configuration at the C-4 position of its substrates because glycosidic derivatives of D-galactose are also hydrolyzed. Does not cleave beta-glycosidic bonds.
