AMYLASES AND GLUCOAMYLASES, NUCLEIC ACIDS ENCODING THEM AND METHODS FOR MAKING AND USING THEM

摘要

In one aspect, the invention is directed to polypeptides having an amylas e and/or glucoamylase activity, polynucleotides encoding the polypeptides, a nd methods for making and using these polynucleotides and polypeptides. In o ne aspect, the polypeptides of the invention can be used as amylases, for ex ample, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosa ccharide or starch into sugars. In one aspect, the invention provides delaye d release compositions comprising an desired ingredient coated by a latex po lymer coating. In alternative embodiments, enzymes are used to make biofuels , e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a b ioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.
