Synthesis of Bacterial Flagella
was developed. This procedure involved measuring the binding of purified, radioactively labeled, antiflagellar antibodies to bacteria. The assay was used to determine the requirements for ribonucleic acid (RNA) and protein synthesis during flagellar regeneration in Bacillus subtilis. Immediate inhibition of flagella development was observed when chloramphenical or puromycin was added to cells. ...
متن کاملSynthesis of bacterial flagella: chromosomal synchrony and flagella synthesis.
Synchronous cultures of Bacillus subtilis 168 M were obtained from light-density spores germinated at 46 C and grown at 37 C. This procedure synchronizes both cell division and chromosome replication. The chromosome synchrony was demonstrated by using transformation to measure changes in marker frequency during the cell cycle. The synthesis of two enzymes and of bacterial flagellar protein was ...
متن کاملPurification and thermal stability of intact Bacillus subtilis flagella.
Flagella were prepared and purified in a relatively intact form from bacterial lysates. Immunochemical tests showed that over 95% of the protein in the final preparation consisted of flagellar antigen. These flagella are more stable to thermal denaturation than flagella filaments obtained by shearing. Their thermal properties more closely resemble those of flagella in the native state on bacter...
متن کاملAntigenic heterology between flagellin and flagella of Bacillus subtilis.
The antigenic properties of Bacillus subtilis flagella and periodate-treated flagellin were compared by using immobilization-inhibition and diethylaminoethyl cellulose binding assay. The results suggest that there are both unique and cross-reactive antibodies elicited by B. subtilis flagella and flagellin.
متن کاملA molecular clutch disables flagella in the Bacillus subtilis biofilm.
Biofilms are multicellular aggregates of sessile bacteria encased by an extracellular matrix and are important medically as a source of drug-resistant microbes. In Bacillus subtilis, we found that an operon required for biofilm matrix biosynthesis also encoded an inhibitor of motility, EpsE. EpsE arrested flagellar rotation in a manner similar to that of a clutch, by disengaging motor force-gen...
