Distribution of proteins according to CAI (A), GRAVY value (B), cellular role categories (C), and localization (D). The whole set of genes encoding proteins (open bars) and identified proteins (black bars) was compared. The single letter codes in C represent a particular functional category as follows: J, translation; A, RNA processing and modification; K, transcription; L, replication, recombination, and repair; D, cell cycle control, mitosis, and meiosis; V, defense mechanisms; T, signal transduction mechanisms; M, cell wall/membrane biogenesis; N, cell motility; U, intracellular trafficking and secretion; O, post-translational modification, protein turnover, chaperones; C, energy production and conversion; 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; P, inorganic ion transport and metabolism; Q, secondary metabolite biosynthesis, transport, and catabolism; R, general function prediction only; S, function unknown; _, not in COG. The meanings of abbreviations in D are as follows: C, cytoplasmic; CM, cytoplasmic membrane; E, extracellular; OM, outer membrane; P, periplasmic; U, unknown; ML, multiple localization sites.
