Essential protein P116 extracts cholesterol and other indispensable lipids for Mycoplasmas
Mycoplasma pneumoniae, responsible for approximately 30% of community-acquired human pneumonia, needs to extract lipids from the host environment for survival and proliferation. A comprehensive structural and functional analysis of the protein P116 by single-particle cryo-electron microscopy reveals a homodimer presenting a previously unseen fold, forming a huge hydrophobic cavity, which is fully accessible to solvent.…
