TLDR
The present study coupled with previously reported results on peptide beta-3T has provided proof that all of the singly linked PEB peptides contain a thioether bond to the 3' position of ring A, and strong evidence in support of a trans-dihydro ring A in each of these chromopeptides.About:

Phycobilisome and Phycobiliprotein Structures
TL;DR: Phycobilisomes serve as the primary light-harvesting antennae for Photosystem II in cyanobacteria and red algae and contain smaller amounts ‘linker polypeptides,’ most of which do not bear chromophores.
Journal ArticleDOI
Structure and function of light‐harvesting complexes and their polypeptides
TL;DR: In this article, a detailed biochemical and structural characterization of the pigment protein complexes of light harvesting antennae was obtained. And the detailed biochemical analysis also allowed a better identification of the various pigmentprotein complexes, which is essential for their isolation.

Extraction and purification of C-phycocyanin from Spirulina platensis (CCC540).
TL;DR: In this study a simple protocol was developed for purifying phycocyanin (PC) from Spirulina platensis by using ammonium sulphate precipitation, followed by a single step chromatography by using DEAE-Cellulose-11 and acetate buffer.

Characterization of the bilin attachment sites in R-phycoerythrin.

TL;DR: The availability of small bilin peptides was exploited to obtain more accurate molar extinction coefficients for peptide-linked PEB and PUB groups, and application of these extinction coefficients in the calculation of the bilin content of R-, B-, and C-phycoerythrins shows that there are 5 bilins/alpha beta in each of these three biliprotein types.

TL;DR: In this paper, a comparative study of the two phycoerythrins of the unicellular red alga Porphyridium cruentum is presented, and it is shown that the presence and amount of phycourobilin chromophores in the native protein is correlated with the presence of the gamma subunit.

TL;DR: Comparison of the sequences from B-phycoerythrin to sequences of several other biliproteins has revealed the presence of a number of invariant tyrosyl and arginyl residues near bilin attachment sites.
