    • The present invention relates to a composition comprising: (a) an X143 polypeptide having retrograded starch degrading activity and (b) a sulfur-containing compound, and/or a heterocyclic compound (reducing agent), wherein the combination of the X143 polypeptide having retrograded starch degrading activity and a sulfur-containing compound and/or a heterocyclic compound (reducing agent), and/or a cellobiose dehydrogenase, enhances degradation of retrograded starch material by the X143 polypeptide. The present invention further relates to a method for degrading or converting a retrograded starch material, comprising: treating the retrograded starch material with an enzyme composition in the presence of an X143 polypeptide having retrograded starch degrading activity and a sulfur-containing compound and/or a heterocyclic compound (reducing agent), and/or a cellobiose dehydrogenase, wherein the combination of the polypeptide having retrograded starch degrading activity and the sulfur-containing compound and/or the heterocyclic compound (reducing agent), and/or the cellobiose dehydrogenase enhances degradation of the retrograded starch material by the enzyme composition.
    • 本发明涉及一种组合物,其包含:(a)具有退化淀粉降解活性的X143多肽和(b)含硫化合物和/或杂环化合物(还原剂),其中所述具有退化的X143多肽的组合 淀粉降解活性和含硫化合物和/或杂环化合物(还原剂)和/或纤维二糖脱氢酶增强了X143多肽对退化淀粉材料的降解。 本发明还涉及一种降解或转化退化淀粉材料的方法,包括:在具有退化的淀粉降解活性的X143多肽和含硫化合物和/或其盐的存在下,用酶组合物处理退化的淀粉材料 杂环化合物(还原剂)和/或纤维二糖脱氢酶,其中具有退化淀粉降解活性的多肽与含硫化合物和/或杂环化合物(还原剂)和/或纤维二糖脱氢酶的组合增强降解 的淀粉原料由酶组成。
