    • A process for producing a urinary human trypsin inhibitor (UTI) and domains thereof by using a yeast of the genus Pichia as the host cell; an expression system related thereto; a novel polypeptide at least having the amino acid sequence represented by formula (I) in the specification; a DNA coding for the same; an expression vector containing the DNA; a transformant containing the vector; and a process for producing the polypeptide. The above UTI, expression system of each domain thereof, and process for producing the UTI and domains thereof enable UTI and domains thereof to be mass-produced readily and efficiently. The use of the expression system facilitates the preparation of variants or derivatives of UTI and so forth and contributes to the development of novel medicines such as a protease inhibitor. The invention also provides a novel useful polypeptide which is more excellent in elastase inhibitory activity than natural UTI and can be mass-produced.
    • 通过使用毕赤酵母属的酵母作为宿主细胞来制备尿胰蛋白酶抑制剂(UTI)及其结构域的方法; 与此有关的表达制度; 至少具有说明书中由式(I)表示的氨基酸序列的新型多肽; 编码相同的DNA; 含有DNA的表达载体; 含有载体的转化体 以及产生该多肽的方法。 上述UTI,其每个结构域的表达系统,以及UTI及其结构域的制备方法使得UTI及其结构域容易且有效地批量生产。 表达系统的使用促进了UTI等变体或衍生物的制备,并有助于新型药物如蛋白酶抑制剂的开发。 本发明还提供了一种与天然UTI相比弹性蛋白酶抑制活性更优异的新型有用多肽,可以批量生产。
