Abstract
Ignicoccus hospitalis forms many cell surface appendages, the Iho670 fibers (width, 14 nm; length, up to 20 mum), which constitute up to 5% of cellular protein. They are composed mainly of protein Iho670, possessing no homology to archaeal flagellins or fimbrins. Their existence as structures different from archaeal flagella or fimbriae have gone unnoticed up to now because they are very brittle.
摘要
医院火球菌形成许多细胞表面附属物，即Iho670纤维（宽度为14纳米；长度可达20微米），其占细胞蛋白质的比例高达5%。它们主要由蛋白质Iho670组成，与古菌鞭毛蛋白或菌毛蛋白没有同源性。由于它们非常脆弱，作为与古菌鞭毛或菌毛不同的结构，它们的存在至今未被注意到。
