NOVELTY - An isolated, synthetic or recombinant nucleic acid, chosen from nucleic acid sequence having 50-99% or 100% sequence identity to sequence (S1) chosen from SEQ ID No. 1, 3, 5, 9-79 (odd SEQ ID Nos) and 80-82, over a region of 25-1550 or more residues, is new.    USE - The nucleic acid (N1) is useful for making an anti-amylase or an anti-glucoamylase antibody and producing a recombinant polypeptide. The primer pair is useful for amplifying a nucleic acid encoding polypeptide (P1). The primer pair and probe are useful for isolating or recovering nucleic acid encoding polypeptide with amylase and/or glucoamylase activity from an environmental sample chosen from water, liquid, soil, air or biological sample derived from bacterial, protozoan, insect, yeast, plant, fungal or mammalian cell. The antisense oligonucleotide is useful for inhibiting translation of amylase and/or glucoamylase message in a cell. The RNAi is useful for inhibiting the expression of an amylase and/or a glucoamylase in a cell. The nucleic acid (N1) and polypeptide (P1) are useful for determining whether a test compound specifically binds to a polypeptide. The polypeptide (P1) is useful as food or feed supplement for animal or human, detergent composition for washing an object, textile or fabric for desizing, paper or paper product or paper pulp for deinking, anti-staling composition for preventing staling of a baked product e.g. bread or bread product, brewing or alcohol production, pharmaceutical composition, oral care products e.g. toothpaste, dental cream, gel or tooth powder, odontic, mouth wash, pre or post brushing rinse formulation, chewing gum, lozenge or candy, oil well drilling fluid, bio-bleaching solution for paper or pulp product, disinfectant, biodefense or bio-detoxifying agent, or dairy product, and for identifying a modulator of an amylase and/or a glucoamylase activity, liquefying or removing a polysaccharide, oligosaccharide or starch from a composition, hydrolyzing a polysaccharide, oligosaccharide or starch in a feed or food comprising rice, corn, barley, wheat, legumes, or potato before consumption by an animal, processing lignocellulosic fibers and improving the fiber properties, producing a high-maltose or a high-glucose syrup, improving the flow of the polysaccharide, oligosaccharide or starch-containing production fluids, changing the viscosity of a composition comprising soil or drilling mud, aiding in the carrying away of drilling mud, making a fuel such as bioethanol, gasoline-ethanol mix, biopropanol, biobutanol or biodiesel, processing a biomass material comprising lignocelluloses, such as biomass material comprising or derived from an agricultural crop, or is a byproduct of a food or a feed production, or lignocellulosic waste product, or plant residue or waste paper or waste paper product, and generating bioethanol, biopropanol, biobutanol, or biodiesel, and for producing a sugar (all claimed).
