- The comparison of the number of genes belonging to the different COG categories revealed only small differences in the genomes of S. cyanea and S. azurea with 0.4% deviation between the same COG categories on average. A slightly higher fraction of genes belonging in the categories transcription (S. cyanea 11.8%, S. azurea 10.6%), carbohydrate metabolism (S. cyanea 7.6%, S. azurea 7.0%), secondary catabolism (S. cyanea 4.5%, S. azurea 4.1%), defense mechanisms (S. cyanea 1.8%, S. azurea 1.6%), inorganic ion transport and metabolism (S. cyanea 4.9%, S. azurea 4.7%) and lipid transport (S. cyanea 4.9%, S. azurea 4.8%) were identified in S. cyanea. The gene count in further COG categories such as cell cycle control, cell motility, cell biogenesis, lipid metabolism, secondary catabolism, post-translational modification and signal transduction was also slightly increased in S. cyanea but differed at most by 5 genes. In contrast, a slightly smaller fraction of genes belonging in the categories posttranslational modification (S. cyanea 3.0%, S. azurea 3.6%), coenzyme metabolism (S. cyanea 4.7%, S. azurea 5.2%), amino acid metabolism (S. cyanea 7.9%, S. azurea 8.4%), replication system (S. cyanea 4.2%, S. azurea 4.7%), translation (S. cyanea 4.3%, S. azurea 4.6%), signal transduction (S. cyanea 4.8%, S. azurea 5.1%), energy production/conversion (S. cyanea 6.3%, S. azurea 6.6%), nucleotide transport (S. cyanea 2.2%, S. azurea 2.4%) and cell wall biogenesis (S. cyanea 4.0%, S. azurea 4.2%) were identified in S. cyanea. The remaining COG categories intracellular transport, cell cycle control, cell motility and RNA modification differed by not more than a single gene.
