The needle length of bacterial injectisomes is determined by a molecular ruler.

Science (New York, N.Y.) - 5 Dec 2003

Journet Laure, Agrain Céline, Broz Petr, Cornelis Guy R

Abstract excerpt

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...
