  abstract = {{B}acteriophytochromes are red/far-red photoreceptors that bacteria use to mediate sensory responses to their light environment. {H}ere, we show that the photosynthetic bacterium {R}hodopseudomonas palustris has two distinct types of bacteriophytochrome-related protein ({R}p{B}ph{P}4) depending upon the strain considered. {T}he first type binds the chromophore biliverdin and acts as a light-sensitive kinase, thus behaving as a bona fide bacteriophytochrome. {H}owever, in most strains, {R}p{B}ph{P}4 does not to bind this chromophore. {T}his loss of light sensing is replaced by a redox-sensing ability coupled to kinase activity. {P}hylogenetic analysis is consistent with an evolutionary scenario, where a bacteriophytochrome ancestor has adapted from light to redox sensing. {B}oth types of {R}p{B}ph{P}4 regulate the synthesis of light harvesting ({LH}2) complexes according to the light or redox conditions, respectively. {T}hey modulate the affinity of a transcription factor binding to the promoter regions of {LH}2 complex genes by controlling its phosphorylation status. {T}his is the first complete description of a bacteriophytochrome signal transduction pathway involving a two-component system.},
