Photosystem I structural fusion with IsiA enhances light-harvesting capabilities of filamentous cyanobacterium during iron deficiency

SUMMARY During iron stress, cyanobacteria produce iron-stress-inducible protein A (IsiA), which associates with photosystem I (PSI) to support cell growth. In most cyanobacteria, the stress induces formation of large IsiA18-PSI3 complexes. However, some species, including Anabaena sp. PCC 7120, studied in this work, fo...
