The light-harvesting state of LHCII is remarkably robust to changes in thylakoid lipid composition and pH.
LHCII is the main antenna complex of plants and green algae. Under low light it maximizes light absorption for photosynthesis, whereas under excess light it becomes the principal site of nonphotochemical quenching (NPQ), a photoprotective process triggered by the acidification of the thylakoid lumen that dissipates exc...
