title: Excretion of unassembled flagellin by Salmonella typhimurium mutants deficient in hook-associated proteins.
abstract: Of the flagellar filamentless mutants of Salmonella typhimurium, the flaV, flaU, and flaW mutants, which are defective in hook-associated proteins, synthesized flagellin molecules, but flagella did not polymerize at the tips of the mutant hooks and were excreted into the culture medium as intact monomers.
