Representation of COG categories among the core genome. Relative representation of COG categories in the whole genome (hatched bars) compared to the core genome (black bars) of S. suis strain P1/7. Representation is calculated as the percentage of genes per COG category compared to the total number of genes in the genome. COG categories: J translation, ribosomal structure and biogenesis; K transcription; L replication, recombination and repair; D cell cycle control, cell division, chromosome partitioning; V defense mechanisms; O posttranslational modification, protein turnover, chaperones; M cell wall/membrane/envelope biogenesis; N cell motility; U intracellular trafficking, secretion, and vesicular transport; T signal transduction mechanisms; C energy production and conversion; P inorganic ion transport and metabolism; G carbohydrate transport and metabolism; E amino acid transport and metabolism; F nucleotide transport and metabolism; H coenzyme transport and metabolism; I lipid transport and metabolism; Q secondary metabolites biosynthesis, transport and catabolism; R general function prediction only; S function unknown; 'other' no COG category attached.
