    Abstract: Modified forms of human interleukin-1.beta. converting enzyme (ICE) that display proteolytic activity and, furthermore, have increased stability compared to unmodified human ICE are disclosed. Nucleic acid molecules encoding a modified p10 subunit of ICE, and recombinant vectors and host cells incorporating such nucleic acid molecules, are also disclosed. A modified ICE protein of the invention can be used to cleave proteolytically ICE substrates and to identify modulators of ICE activity in screening assays. Moreover, due to its enhanced stability, the modified ICE of the invention is particularly suitable for use in the preparation of ICE crystals for X-ray crystallography.

    Abstract translation: 公开了与未修饰的人类ICE相比显示出蛋白水解活性的人白细胞介素-1β转换酶(ICE)的修饰形式,此外具有增加的稳定性。 还公开了编码ICE的修饰的p10亚基的核酸分子,以及掺入了这种核酸分子的重组载体和宿主细胞。 本发明的修饰的ICE蛋白质可用于切割蛋白水解的ICE底物并鉴定筛选测定中ICE活性的调节剂。 此外,由于其稳定性的提高,本发明的改性ICE特别适用于制备用于X射线晶体学的ICE晶体。
