Phycobiliproteins encapsulated in sol-gel glass [PDF]

, 1996
Light transducing phycobiliproteins are encapsulated in optically transparent sol-gel matrices. Absorption and fluorescence spectroscopies are used to characterize the effect of the sol-gel encapsulation on the conformation and aggregation states of the ...

Modular generation of fluorescent phycobiliproteins [PDF]

, 2013
Phycobiliproteins are brightly-fluorescent light-harvesting pigments for photosynthesis in cyanobacteria and red algae. They are also of interest as fluorescent biomarkers, but their heterologous generation in vivo has previously required multiple ...

Phycobiliprotein Lyases [PDF]

, 2008
Phycobilins are light harvesting pigments of cyanobacteria and red algae. In cyanobacteria, four phycobiliproteins are organized in phycobilisomes: phycocyanin (PC), allophycocyanin (APC), and often also phycoerythrocyanin (PEC) or phycoerythrin (PE ...

FLUORESCENCE AND CIRCULAR DICHROISM STUDIES ON THE PHYCOERYTHROCYANINS FROM THE CYANOBACTERIUM [PDF]

, 1993
Two phycoerythrocyanin (PEC) fractions have been obtained from the phycobilisomes of the cyanobac-terium Westiellopsis prolifica ARM 365. They have been characterized by absorption, fluorescence and circular dichroism spectroscopy.
