description | The pathogenic bacterium
Legionella pneumophila
replicates in host cells within a distinct ER‐associated compartment termed the
Legionella
‐containing vacuole (LCV). How the dynamic ER network contributes to pathogen proliferation within the nascent LCV remains elusive. A proteomic analysis of purified LCVs identified the ER tubule‐resident large GTPase atlastin3 (Atl3, yeast Sey1p) and the reticulon protein Rtn4 as conserved LCV host components. Here, we report that Sey1/Atl3 and Rtn4 localize to early LCVs and are critical for pathogen vacuole formation. Sey1 overproduction promotes intracellular growth of
L. pneumophila
, whereas a catalytically inactive, dominant‐negative GTPase mutant protein, or Atl3 depletion, restricts pathogen replication and impairs LCV maturation. Sey1 is not required for initial recruitment of ER to PtdIns(4)
P
‐positive LCVs but for subsequent pathogen vacuole expansion. GTP (but not GDP) catalyzes the Sey1‐dependent aggregation of purified, ER‐positive LCVs
in vitro
. Thus, Sey1/Atl3‐dependent ER remodeling contributes to LCV maturation and intracellular replication of
L. pneumophila
.

replicates within a distinct ER‐associated compartment, the
Legionella

The ER tubule‐resident large GTPase Atlastin3/Sey1 localizes to LCVs and enhances intracellular replication of
