1. Violaxanthin de-epoxidase and its closest relative: identification and characterization
Abstract : Light is essential for plants and algae to process photosynthesis. However, excess of light will cause damage to the organism. A process called non-photochemical quenching (NPQ) is an important way for these organisms to protect themselves from photo oxidative damage. READ MORE

2. Light Protection in Plants: Characterisation of Violaxanthin de-epoxidase
Abstract : Plants and algae need light to drive the photosynthetic machinery. An excess of light will, however, result in damage to the photosynthetic machinery and to the rest of the organism. The surplus of energy, when exposed to light stress is converted into less harmful heat energy through a process called non-photochemical quenching. READ MORE

3. Violaxanthin De-epoxidase and the Xanthophyll Cycle
Abstract : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. READ MORE

4. Xanthophyll Cycle in the Light of Thylakoid Membrane Lipids - Membrane Packing, Curvature Elastic Stress and Enzyme Binding
Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. The enzyme, violaxanthin de-epoxidase (VDE) catalyses the conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin. VDE is a membrane-hosted enzyme during its activity. READ MORE

5. The significance of feedback de-excitation
Abstract : During photosynthesis sunlight is absorbed by photosynthetic pigments and converted into organic compounds, such as carbohydrates. Photosynthesis needs to be highly regulated, since both too much and too little light are harmful to plant. READ MORE
