What role does sulpholipid play within the thylakoid membrane?

abstract：:The thylakoid membrane protein PsbS is critical for quenching excessive excitation energy in mechanisms that involve the light-harvesting complexes of photosystem II. Liposomes of thylakoid lipids have been shown to be a very good platform to study photosynthetic membrane proteins and their interactions. In this study...
