    • The present invention relates to methods of making heparin-binding protein (HBP) in a recombinant bacterial expression system. In particular, this invention relates to a method for the preparation of an insoluble fusion protein comprising heparin-binding protein (HBP), a proteolytic cleavage- site, and a second polypeptide in recombinant bacterial cells, said fusion protein being accumulated in inclusion bodies in the cytoplasm of bacterium after expression. The invention further relates to methods of separation of the expressed HBP from inclusion bodies comprising purification of HBP from the second polypeptide and optionally refolding of said HBP. The invention further features the DNA constructs comprising different HBP-fusion proteins. Invention also relates to use of the HBP-fusion protein produced in bacteria for the production of pure HBP and use of the HBP purified from the fusion protein for the preparation of a medicament.
    • 本发明涉及在重组细菌表达系统中制备肝素结合蛋白(HBP)的方法。 特别地,本发明涉及在重组细菌细胞中制备包含肝素结合蛋白(HBP),蛋白水解切割位点和第二多肽的不溶性融合蛋白的方法,所述融合蛋白被积累在包含体内 表达后细菌的细胞质。 本发明还涉及从包含体分离表达的HBP的方法,包括从第二多肽纯化HBP并任选地重新折叠所述HBP。 本发明还涉及包含不同HBP融合蛋白的DNA构建体。 本发明还涉及在细菌中产生的HBP-融合蛋白用于生产纯HBP和使用从融合蛋白纯化的HBP用于制备药物的用途。

    • A process for expression of a protein product in Aspergillus is disclosed. The process comprises transforming an Aspergillus strain with a vector system comprising DNA-sequences encoding a promoter including upstream activating sequences derived from an A. niger amylase, a suitable marker for selection of transformants, and a DNA-sequence encoding the desired protein product. The process enables industrial production of many different polypeptides and proteins in Aspergillus, preferably A. niger. Examples of such products are chymosin or prochymosin and other rennets, proteases, lipases and amylases. Also disclosed is an effective promoter for expression of a protein in Aspergillus, preferably Aspergillus niger being derived from a gene encoding an A. niger amylase. The A. niger amylases are the neutral and acid stable alpha -amylases and a new amylase not so far described and designated XA amylase. Also disclosed is the novel amylase from A. niger XA amylase.
    • 公开了在曲霉中表达蛋白质产物的方法。 该方法包括用包含编码启动子的DNA序列的载体系统转化曲霉菌菌株,所述启动子包括来自黑曲霉淀粉酶的上游活化序列,用于选择转化体的合适标记物和编码所需蛋白质产物的DNA序列。 该方法使得能够在曲霉属中产生许多不同的多肽和蛋白质,优选黑曲霉。 这些产品的实例是凝乳酶或凝乳酶原和其他雷诺丝,蛋白酶,脂肪酶和淀粉酶。 还公开了用于在曲霉中表达蛋白质的有效启动子,优选来自编码黑曲霉淀粉酶的基因的黑曲霉(Aspergillus niger)。 黑曲霉淀粉酶是中性和酸稳定的α-淀粉酶和不是迄今描述的新的淀粉酶,并且被称为XA淀粉酶。 还公开了来自黑曲霉XA淀粉酶的新型淀粉酶。
