Two of the psbA sequences (AM1 2166 and AM1 2889) share 97 nucleotide and 100 amino acid identity, whereas the third (AM1 0448) shares only 61 amino acid identity and is more closely related to a divergent PsbA in Anabaena variabilis (YP 324615) and Crocosphaera watsonii (ZP 00515211). Two of the psbD sequences (AM1 1083 and AM1 4084) share 99 nucleotide and 100 amino acid ident
