Abstract excerpt
Proteorhodopsin (PR), a photoactive proton pump containing retinal, is present in approximately half of all bacteria in the ocean, but its physiological role is still unclear, since very few strains carrying the PR gene have been cultured. The aim of this work was to characterize PR diversity in a North Sea water sample, cultivate a strain representative of North Sea PR clusters, and study the effects of light...
