abstract = {Gram-negative pathogens evolved a syringe-like nanomachine,
termed type 3 secretion system, to deliver protein effectors
into the cytoplasm of host cells. An essential component of
this system is a long helical needle filament that protrudes
from the bacterial surface and connects the cytoplasms of
the bacterium and the eukaryotic cell. Previous structural
research was predominantly focused on reconstituted type 3
needle filaments, which lacked the biological context. In
this work we introduce a facile procedure to obtain
high-resolution cryo-EM structure of needle filaments
attached to the basal body of type 3 secretion systems. We
validate our approach by solving the structure of Salmonella
PrgI filament and demonstrate its utility by obtaining the
first high-resolution cryo-EM reconstruction of Shigella
MxiH filament. Our work paves the way to systematic
structural characterization of attached type 3 needle
filaments in the context of mutagenesis studies, protein
structural evolution and drug development.},
