  • Anionic phospholipids stimulate the proton pumping activity of the plant plasma membrane P-type H+-ATPase

    • Authors : Paweletz, Laura C. (2023)

  • The activity of membrane proteins depends strongly on the surrounding lipid environment. Here, we characterize the lipid stimulation of the plant plasma membrane H+-ATPase AHA2 upon purification and reconstitution into liposomes of defined lipid compositions. We show that the proton pumping activity of AHA2 is stimulated by anionic phospholipids, especially by phosphatidylserine. Molecular dynamics simulations revealed several preferential contact sites for&#...

  • Screening of candidate host cell membrane proteins involved in SARS-CoV-2 entry

    • Authors : Kotani, Norihiro (2023)

  • Coronavirus disease (COVID-19) represents a real threat to the global population, and understanding the biological features of the causative virus, i.e., severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is imperative for mitigating this threat. Analyses of proteins such as primary receptors and co-receptors (co-factors), which are involved in the entry of SARSCoV- 2 into host cells, will provide important clues to help control the virus. Here,&#...

  • Structural characterization of the antimicrobial peptides myxinidin and WMR in bacterial membrane mimetic micelles and bicelles

    • Authors : Cherniavskyi, Yevhen K. (2021)

  • Antimicrobial peptides are a promising class of alternative antibiotics that interact selectively with negatively charged lipid bilayers. This paper presents the structural characterization of the antimicrobial peptides myxinidin and WMR associated with bacterial membrane mimetic micelles and bicelles by NMR, CD spectroscopy, and Molecular Dynamics simulations. Both peptides adopt a different conformation in the lipidic environment than in aqueous solution. The...
