Genetic analysis defines sites of charge-based interaction between LolA and LolB proteins in lipoprotein trafficking

Ethan A. Rundell, Julianna Marotta, Kerrie L. May…·Marcin Grabowicz

The paper identifies critical charge-based interactions between LolA and LolB proteins in lipoprotein trafficking by screening mutations in LolB and showing that charge reversals in LolA can suppress lethality.

Genetic analysis reveals a robust and hierarchical recruitment of the LolA chaperone to the LolCDE lipoprotein transporter

Kelly M. Lehman, Kerrie L. May, Julianna Marotta, Marcin Grabowicz

The paper challenges a bipartite model of LolC-LolA interaction by showing the Hook is essential while the Pad is ancillary in lipoprotein trafficking in E. coli.
