Table 2 COG functional categories. COG (Clusters of Orthologous Genes) functional categories of chromosomal protein codding sequences identified in S. leeuwenhoekii chromosome, and from S. coelicolor for comparison (as calculated by BASys [25] for both genomes)

From: The Streptomyces leeuwenhoekii genome: de novo sequencing and assembly in single contigs of the chromosome, circular plasmid pSLE1 and linear plasmid pSLE2
