Cryo-EM structures of LolCDE reveal the molecular mechanism of bacterial lipoprotein sorting in Escherichia coli
Fig 7
Proposed model for lipoprotein extraction and transfer to LolA.
ATP and ADP are shown as balls in red and purple, respectively. The dashed arrow indicates the path for lipoproteins entry into the cavity. Our apo-LolCDE, RcsF-LolCDE and AMPPNP-LolCDE structures represent structures in ①, ②, and ③, respectively.
