Abstract excerpt

The two reaction-centre proteins of the photosystem I (PSI) complex are encoded by two adjacent genes named psaA and psaB. We have performed targeted mutagenesis to insertionally inactivate each of these genes in the filamentous cyanobacterium Anabaena variabilis ATCC 29413. The resulting mutant strains, termed psaA::NmR and psaB::NmR, were blue because of a high ratio of phycobilin to chlorophyll and were unable...
