CC -!- FUNCTION: Regulatory photoreceptor which exists in two forms that are
CC reversibly interconvertible by light: the R form that absorbs maximally
CC in the red region of the spectrum and the FR form that absorbs
CC maximally in the far-red region. Has also a slight blue shift for the
CC far-red maximum. Forms a two-component system with the Rrcp1 response
CC regulator.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC histidine.; EC=2.7.13.3;
CC -!- SUBUNIT: Homodimer.
CC -!- INTERACTION:
CC Q55168; Q55168: cph1; NbExp=8; IntAct=EBI-594457, EBI-594457;
CC Q55168; Q55169: rcp1; NbExp=2; IntAct=EBI-594457, EBI-766949;
CC -!- PTM: Contains one covalently linked tetrapyrrole chromophore.
CC {ECO:0000250}.
CC -!- MISCELLANEOUS: The R form exhibits both ATP-dependent
CC autophosphorylation and phosphotransfer to Rcp1 activities. Unlike the
CC higher plants where Pfr is thought to be the active form.
CC -!- SIMILARITY: In the N-terminal section; belongs to the phytochrome
CC family. {ECO:0000305}.
