Antigenic 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 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 کاملAmino acid substitutions and intragenic duplications of Bacillus sp. PS3 flagellin cause complementation of the Bacillus subtilis flagellin deletion mutant.
Bacillus sp. PS3 produces a glycosylated flagellin. In this study, a number of the glycosylated residues of the flagellin protein were found to be located in the central variable region of this protein. We also report that the motility defect of the Bacillus subtilis flagellin mutant was complemented by Bacillus sp. PS3 flagellin variants without glycosylation, which contained amino acid substi...
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...
متن کاملHeterologous expression of antigenic peptides in Bacillus subtilis biofilms
BACKGROUND Numerous strategies have been developed for the display of heterologous proteins in the surface of live bacterial carriers, which can be used as vaccines, immune-modulators, cancer therapy or bioremediation. Bacterial biofilms have emerged as an interesting approach for the expression of proteins of interest. Bacillus subtilis is a well-described, endospore-forming organism that is a...
