2010年1月14日 · Here we describe the three-dimensional solution structure of the bilin-binding domain as Pfr, using the cyanobacterial phytochrome from Synechococcus OSB′. Contrary to …

2020年5月4日 · We designed various constructs of Sorghum bicolor (Sb) and Glycine max (Gm) phyA and phyB sensory modules for expression as phycocyanobilin (PCB) or …

2023年1月18日 · Cph1 phytochrome shows a photoisomerization of its phycocyanobilin (PCB) chromophore in the Pfr state with a time constant of 0.7 ps. The dynamics of the PCB …

光敏色素蛋白大小大约为125 kDa，可以通过一个非常保守的半胱氨酸共价结合一个小分子（在蓝藻中是phycocyanobilin 即PCB，而在高等植物中是phytochromobilin 即PΦB）。 在黑暗中， …

2017年10月20日 · Whereas incorporation of the native bilin phytochromobilin into PhyB confers robust Pfr → Pr thermal reversion, that assembled with the cyanobacterial version …

光敏色素有红光吸收型(Pr)和远红光吸收型(Pfr)两种构象形式，Pr吸收红光后转变为Pfr，Pfr吸收远红光后转变为Pr。 人们通常认为Pfr是光敏色素的活性形式。

2002年2月1日 · For the experiments on Cph1-PCB-Pfr, both excitation and probe pulses were provided by a white light continuum with an IRF of ∼500 fs FWHM. The IRF was controlled …
