Circular genome maps of Caulobacter flavus RHGG3. Rings from the outermost to the center: (1) scale marks of the genome, (2) protein-coding genes on the forward strand, (3) protein-coding genes on the reverse strand, (4) rRNA operon and tRNA genes, (5) GC content, and (6) GC skew. Circles 2 and 3 are open reading frames encoded by leading and lagging strands, respectively, with color codes for the COG functional categories: A, RNA processing and modification; B, chromatin structure and dynamics; J, translation, ribosomal structure and biogenesis; K, transcription; L, replication, recombination and repair; D, cell cycle control, cell division, chromosome partitioning; M, cell wall/membrane/envelope biogenesis; N, cell motility; O, posttranslational modification, protein turnover, chaperones; T, signal transduction mechanisms; U, intracellular trafficking, secretion, and vesicular transport; V, defense mechanisms; Z, cytoskeleton; C, energy production and conversion; E, amino acid transport and metabolism; F, nucleotide transport and metabolism; G, carbohydrate transport and metabolism; H, coenzyme transport and metabolism, I, lipid transport and metabolism; P, inorganic ion transport and metabolism; Q, secondary metabolite biosynthesis, transport and catabolism; R, general function prediction only; and S, function unknown
