Evidence Snippets

In this review we give an overview of the knowledge on the functioning of photosensors in microorganisms, with special emphasis on the conformational changes that lead to signal generation and transduction.

Claim 1classification summarysupports1996Source 1DOI PubMed

The chromophores used in microbial photosensing described in the review fall into three classes: tetrapyrroles, polyenes, and aromatics.

These chromophores belong to three classes: tetrapyrroles, polyenes and aromatics.

Claim 2knowledge gapsupports1996Source 1DOI PubMed

By 1996, structural knowledge for several physiologically characterized UV- and blue-light photoreceptors in microorganisms was still lacking.

Quoted textsource-backed

However, knowledge about the structure of photoreceptors responsible for several physiologically well-characterized photoresponses to UV- and blue light is still lacking.

Claim 3mechanistic summarysupports1996Source 1DOI PubMed

Microbial photosensors initiate signalling through light absorption by specific chromophores whose protein environment tunes their function, coupled to conformational changes that generate and transduce signal.

Quoted textsource-backed

Light is absorbed by specific chromophores, which are tuned, by their proteinaceous environment, to function optimally... with special emphasis on the conformational changes that lead to signal generation and transduction.
