  1. * Missing in 1-2 strains/isolates
  2. + These proteins are primarily present in various Synechococcus species/strains that are part of Clade C (see Figs. 1 and 2). However, Synechococcus genus is not monophyletic and many Synechococcus strains group with Clade and B (viz. Synechococcus sp. PCC7002, Synechococcus sp. PCC7335, Synechococcus sp. JA-3-3Ab and JA-2-3B'a) and these proteins are absent in those strains. Besides Synechococcus, homologs of many of these proteins are also found in Cyanobium sp. PCC7001 as well as in Paulinella chromatophora, indicating that these species may also belong to the Clade C cyanobacteria.
