要旨:
Sensory photoreceptors occur in all kingdoms of life, eliciting diverse organismal adaptations in response to incident light. The recently identified cyanobacteriochromes (CBCRs) mediate photochromatic and phototactic responses in cyanobacteria (1–3). Great strides toward a molecular understanding of photoreception and signal transduction in this spectrally diverse and exciting photoreceptor family have now been taken by Narikawa et al. (4), who report high-resolution structures of two CBCR photosensor modules in PNAS.
