In Synechocystis 6803 the psbA gene, encoding the Dl polypeptide of the Photosystem II reaction center, belongs to a multigene family with three copies (1). The nucleotide sequence of psbA-1 has been reported (2). We have cloned and seguenced a seconcl psbA gene, psbA-2. front Svnechocvstis 6803. The second copy of psbA i s contained within a 2.1 Kb genomic Hind III fragment. The psbA-2 open reading frame is highly homologous to psbA genes from other cyanobacteria and higher plants.
