Abstract EN
Phycobilisome is the major light-harvesting complex in cyanobacteria and red alga.
It consists of phycobiliproteins and their associated linker peptides which play key role in absorption and unidirectional transfer of light energy and the stability of the whole complex system, respectively.
Former researches on the evolution among PBPs and linker peptides had mainly focused on the phylogenetic analysis and selective evolution.
Coevolution is the change that the conformation of one residue is interrupted by mutation and a compensatory change selected for in its interacting partner.
Here, coevolutionary analysis of allophycocyanin, phycocyanin, and phycoerythrin and covariation analysis of linker peptides were performed.
Coevolution analyses reveal that these sites are significantly correlated, showing strong evidence of the functional and structural importance of interactions among these residues.
According to interprotein coevolution analysis, less interaction was found between PBPs and linker peptides.
Our results also revealed the correlations between the coevolution and adaptive selection in PBS were not directly related, but probably demonstrated by the sites coupled under physical-chemical interactions.
