Photosystem I structural fusion with IsiA enhances light-harvesting capabilities of filamentous cyanobacterium during iron deficiency
Analysis of energetic properties of gel-embedded supercomplexes demonstrated that excitation energy transfer in the IsiA-PsaL complex is highly efficient, suggesting enhanced efficiency may be a key factor underlying the downsizing of the IsiA-PSI assembly, which could compensate for the smaller size of the complex.
