cpcE and cpcF encode subunits of the phycocyanobilin
lyase that incorporates bilin pigment into the complex.

Thus, the presence of D-glucose caused a reduction of pigment content in the cell, due to the inhibition of chlorophyll a and phycocyanobilin
biosynthesis at the stage of the transformation of their universal precursor.
Oxygen radical absorbance capacity of phycocyanin and phycocyanobilin
from the food supplement Aphanizomenon flos-aquae.
(PCB) was prepared from Spirulina platensis extracts by methanolysis as described  and used as chromophores for the holo-phytochrome assembly.

prepared from Spirulina platensis.
We have previously demonstrated that phycocyanobilin
, a natural tetrapyrrolic compound similar to bilirubin, can attenuate the levels of mitochondrial superoxide and consequently shift the glutathione redox buffer towards reduction .
This protein contains a tetrapyrrole phycocyanobilin
, which is responsible for antioxidant properties of Pc .
