Polymerized flagellin

Phe, G)-Pro-L, poly-1-(Phe, Glu)-poly-l-Pro-poly-l-Lvs POL, polymerized flagellin PVP, polyvinylpyrrolidone R anti-POL, rabbit-anti-POL antibody R anti-MIg, rabbit anti-mouse-Ig antibody Rd, tetramethylrhodamine (isothiocyanate)... 

The polymerization of flagellin to flagellum and that of tubulin to microtubule are also endothermic. The monomer-monomer bond free energy is of the same order as that in F-actin, although the dependency on the salt concentration is different in each. 

Since then, the polymerization of various protein molecules was found to have similar features. There is a critical concentration for polymerization and the polymerization consists of nucleation and growth. Bacterial flagella are helically curved tubular polymers of flagellin molecules. Flagella are formed from purified flagellin molecules in solution, although spontaneous nucleation of flagella can hardly occur [10]. The polymerization of tubulin molecules to microtubules is...
