Phyco Biotech is one of the few companies in the world specialized in the extraction and purification of phycobiliproteins, fluorescent labels of natural origin. We offer four types of phycobiliproteins:
Phycobiliproteins, astonishing molecules
Phycobiliproteins are natural polymeric proteins found in cyanobacteria, eucaryotic red algae and cryptomonads where they represent accessory photosynthetic pigments. Within the algae, they are comprised of stacks of phycobiliproteins organized around an architecture named phycobilisomes the natural light harvesting complexes.
Phycobiliproteins are made up of a high molecular weight protein backbone to which open tetrapyrrolic chromophores are covalently bound.
The main phycobiliproteins are allophycocyanin (APC), the phycocyanins family (C-PC and R-PC), the phycoerythrins family (R-PE and B-PE) and phycoerythrocyanin (PEC).
Within the phycobilisome, the phycobiliproteins are geometrically arranged in a manner that optimize the capture of light and energy transfer. Thus, they capture the incident light in wavelength domains poorly efficient for chlorophyll. By fluorescence cascade, this energy is transferred to the photosynthetic reaction center and to the chlorophyll a.
This energy transfer chain within the phycobilisome is :
phycoerythrin -> phycocyanin -> allophycocyanin -> chlorophyll a.
