In one aspect, the invention is directed to polypeptides having an amylase and/or glucoamylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. In one aspect, the polypeptides of the invention can be used as amylases, for example, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosaccharide or starch into sugars. In one aspect, the invention provides delayed release compositions comprising an desired ingredient coated by a latex polymer coating. In alternative embodiments, enzymes are used to make biofuels, e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a bioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.
