Keeping an “eye” on the structure and role of visual cycle proteins

The structure and role of visual cycle proteins. AoS

Opsins are ocular proteins in photoreceptors that transform light energy to initiate signals for vision. Each opsin contains an 11-cis-retinal chromophore which is converted into all-trans-retinal when activated by a photon. The all-trans-retinal must be recycled back

Chloroplast movements after blue light pulses give new insights into the photoreceptor functioning

Plants rely on light as a source of energy. The availability of light is often a limiting factor for the process of photosynthesis. However, too much light can cause cell damage. Plants have numerous mechanisms of adjusting
