Occurrence of photo reversible absorption changes in dissociated allo phycocyanin and phycocyanin



Occurrence of photo reversible absorption changes in dissociated allo phycocyanin and phycocyanin



Photochemistry & Photobiology 38(5): 605-608



The photochromic response of allophycocyanin (APC) and phycocyanin (PC) was studied. Phycobiliproteins were isolated from the blue-green alga Tolypothrix tenuis and supplementarily from Anabaena cylindrica. The response was found in both APC and PC when they were dissociated into monomer in the presence of propylene glycol at a high concentration. APC in propylene glycol solution showed 2 photoresponses identical with those of phycochromes c and d, respectively. PC showed the photoresponse phycochrome a type. After re-association by removal of propylene glycol, photoresponse activities disappeared. It was concluded that some of monomer APC's and PC's became photoreactive when APC and PC were dissociated into monomer, and that photoresponses of phycochromes a, c and d were not attributed to the special pigments independent of APC and PC, but were responsible to special molecules of monomer APC and PC. Spectral patterns of photoresponses were discussed in relation to dissociation-association of protein.
