The presence or absence of a corresponding homologous E. coli gene in cyanobacteria was determined by BLASTP using KEGG with a probability cut-off with an E-value of 2e−10 and at least 50% amino acid sequence similarity as compared to the full-length translation product of the corresponding E. coli gene. The minus sign (−) indicates that a gene satisfying the above criteria was not found. 6803, Synechocystis sp. PCC 6803; 7942, Synechococcus elongatus PCC 7942; 7002, Synechococcus sp. PCC 7002; 7120, Anabaena sp. PCC 7120.
