    • 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。
