Flagellar toxicity: Flagellar synthesis is lytic for Bacillus subtilis in the absence of PBP1.
Flagella are large transenvelope nanomachines but how they transit the peptidoglycan in gram-positive bacteria is poorly understood. A recent model suggested that flagellar basal bodies diffuse in the membrane and become captured at locations in the peptidoglycan with a pore diameter that could accommodate the axle-lik...
