Abstract
Size determination represents a fundamental requirement for multicomponent biological structures. Some pathogenic bacteria possess a weapon derived from the flagellum. Like the flagellum, this type-III secretion apparatus, called the injectisome, has a transmembrane basal body, but the external component is a needle-like structure instead of a hook and a filament. Here, we provide evidence that the length of this needle is determined by the size of a protein, YscP, acting as a molecular ruler.

However Yop secretion is only triggered upon contact with a target cell or artificially by chelating Ca 2+ ions. The usual procedure consists of growing bacteria at 28°C in oxalated rich medium and then switching the culture to 37°C. In these secretion-permissive conditions the production of injectisomes is also stimulated. When bacteria are grown at 37°C in the presence of 5 mM Ca 2+ they make injectisomes but they do not secrete Yops (nonpermissive conditions). Materials and methods are available as supporting material on Science Online.
