Protein

Phytochrome-like protein cph1

Gene

cph1

Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light: the R form that absorbs maximally in the red region of the spectrum and the FR form that absorbs maximally in the far-red region. Has also a slight blue shift for the far-red maximum. Forms a two-component system with the rcp1 response regulator.

Catalytic activityi

ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.
