Nettet22. aug. 2015 · Phytochromobilin is a linear tetrapyrrole and is the chromophore of phytochrome, absorbing red and far red light (Terry et al. 1993). The four pyrrole rings of chlorophyll are connected to form a tetrapyrrole ring with an Mg 2+ in the center. The fourth ring of the tetrapyrrole is esterified with phytol. NettetCyanobacteriochromes are compact and spectrally diverse photoreceptor proteins that bind a linear tetrapyrrole as a chromophore. They show photochromicity by having two stable states that can be interconverted by the photoisomerization of the chromophore. These photochemical properties make them an attractiv
