Bacterial secretion articles from across Nature Portfolio

Bacterial secretion is the process by which bacteria release substances to their surroundings, including other cells. Bacteria achieve this using dedicated secretion systems that transport molecules – such as factors involved in bacterial pathogenesism, so called effectors – across the cell wall.

    The type three secretion system (T3SS) is a membrane-anchored nano-machine utilized by many pathogenic bacteria to inject effector proteins and thus take control of host cells. In a recent article, Kaval et al. reveal a striking colocalization of a T3SS-encoding locus, its transcriptional activators, protein products, and the complete structure at the cell membrane, which they claim provides evidence for a mechanism known as ‘transertion’.
