WebDec 1, 2001 · The regulation of flagellar assembly may be at least as complex as the regulation of flagellar beating (for review, see Asleson and Lefebvre, 1998). For example, when one of the two flagella is amputated, the other one immediately begins to resorb into the cell, while the replacement for the amputated flagellum begins to regrow. At some … WebJul 18, 2024 · The assembly of the axial structure begins with the rod, followed by the hook and finally the filament. A type III protein export apparatus is located at the flagellar base and transports flagellar axial proteins from the cytoplasm to the distal end of the growing flagellar structure where their assembly occurs. WebOct 22, 2024 · A regulatory network involving more than 60 genes controls flagellar assembly. The most important member of the network is the master operon, flhDC , which encodes the FlhD 4 C 2 protein. FlhD 4 C 2 controls the construction of flagella by initiating the production of hook basal bodies (HBBs), protein structures that anchor the flagella to … dying tooth treatment
