Identification and localization of flagellins FlaA and FlaB3 within flagella of Methanococcus voltae

Results reveal the presence of two new of the four flagellins in Methanococcus voltae. The flagellin FlaA is distributed throughout the filament whereas FlaB3 appears to be seen in the proximal end of the cell surface, perhaps similar to the bacterial hook. Both FlaA and FlaB3 are structural components of the flagella.
