Functional divergence of LhcSR and PsbS in zeaxanthin-mediated non-photochemical quenching
{{output}}
To protect photosystem II from excess light, non-photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light-regulated xanthophyll cycle, which interconverts violaxan... ...
