Keyword - Archaeal flagellum (KW-0974)


Archaeal protein present in a flagellum, a long hair-like cell surface appendage made of polymerized flagellin with an attached hook. This rotating structure with switches propels the cell through a liquid medium. The archaeal flagellum is distinct from its bacterial equivalent in terms of architecture, composition and mechanism of assembly. Thinner (10-15 nm) compared to the bacterial flagellum (18-24 nm), it is usually composed of several types of flagellins and is glycosylated. The archaeal flagellum is considered as a type IV pilus-like structure.
