특징적인 운동성 고찰
* CHEMOTAXIS (E. coli and Salmonella)

* Gliding Motility
* Pili or Fimbriae
Bacterial (Prokaryotic) Flagella - extending structure:
E. coli and S. enteritica
M, S ring (<- Flh C, Flh D)
-> adding switch proteins
Export apparatus – Flh A, Fli H, Fli I
Proximal and distal rods – Flg B, Flg C, Flg F, Flg G
* RIVET – simplest isolated structure
Fli F, Fli E, Four rods
P, L ring (<- Flg I, Flg H)
-> primary cellular export pathway
Filament (bacterial flagella) – 100% protein (flagellin)
Structural characteristics of bacterial filaments
Densely packed subunits
Inner part: dense core 30-50Å radius
Distal end of filament: flagellar growth
Hook – 3 types protein
Hook-associated proteins (HAPS 1, 2, 3)
Cap structure
Outer ring
Core region –”Flagellum specific pathway”
