A semiempirical approach to the intra-phycocyanin and inter-phycocyanin fluorescence resonance energy-transfer pathways in phycobilisomes
2007
Journal of Computational Chemistry
A semiempirical methodology to model the intra-phycocyanin and inter-phycocyanin fluorescence resonance energy-transfer (FRET) pathways in the rods of the phycobilisomes (PBSs) from Fremyella diplosiphon ...
Protein docking predicted the quaternary structure for PCs in rods with inter-phycocyanin distance of 55.6 Å and rotation angle of 20.58. ...

Electronic coupling of the phycobilisome with the orange carotenoid protein and fluorescence quenching
2015
Photosynthesis Research
, the time of the direct energy transfer from the phycobilin of PBL CM to the S 1 excited state of hECN was semiempirically calculated to be 36 ps, which corresponds to the known experimental data and ...
Using computational modeling and known 3D structure of proteins, we arrived at a rational spatial model of the orange carotenoid protein (OCP) and phycobilisome (PBS) interaction in the non-photochemical ...
