摘要:革兰氏阴性菌铜绿假单胞菌的感染导致免疫受损的患者和囊性纤维化患者的高死亡率.病原体可以从浮游生物转变为生物膜,从而保护自己免受抗生素治疗并宿主免疫防御以建立慢性感染.细菌蛋白leca,一种c型凝集素,是一种致病因子,是生物膜形成不可或缺的组成部分.leca及其碳水化合物配体的抑制作用导致生物膜质量降低,这可能是治疗的潜在致命弱点.在这里,我们报告与leca的荧光偏振为基础的竞争性结合测定法的发展和优化,用于筛选潜在的抑制剂.由于d的亲和力低对于leca-半乳糖,优化荧光配体以减少测定中的蛋白质消耗.使用一组已知的leca抑制剂验证了该测定,并获得了与已知k D值高度吻合的ic 50值.最后,我们采用了优化的检测方法来筛选合成的硫代半乳糖苷和天然血型抗原的集合,并报告它们的结构-活性关系.此外,我们评估了leca的多价荧光测定探针,并报告了其在抑制测定中的适用性.

摘要:The present invention relates to combinatorial variants of a parent glucoamylase that have altered properties for reducing the synthesis of condensation products during hydrolysis of starch. Accordingly the variants of a parent glucoamylase are suitable such as for use within brewing and glucose syrup production. Also disclosed are DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.

摘要:Provided is a method for quantitating a saccharide in a liquid sample. The method comprises incubating the liquid sample with 2,3-naphthalenediamine in the presence of iodine to allow a naphthimidazole group to be linked to the saccharide to obtain a first mixture; obtaining an 1 H-NMR spectrum of the first mixture; and comparing, in said 1 H-NMR spectrum, the intensity or integral of a proton signal corresponding to the saccharide to the intensity or integral of a proton signal corresponding to an internal standard present in the first mixture.
