Functional category distribution of proteins identified from F1 cells grown in LB or M9L media in the absence of chromate. Letters along the x-axis refer to the following functional role categories: (v) defense mechanisms; (u) intracellular trafficking, secretion and vesicular transport; (t) signal transduction mechanisms; (s) unknown function; (r) general function prediction; (q) secondary metabolite biosynthesis, transport and catabolism; (p) inorganic ion transport and metabolism; (o) post-translational modification, protein turnover, and chaperones; (n) cell motility; (m) cell wall membrane and envelope biogenesis; (l) DNA replication, recombination and repair; (k) transcription; (j) translation of ribosomal structure and biogenesis; (i) lipid transport and metabolism; (h) coenzyme transport and metabolism; (g) carbohydrate transport and metabolism; (f) nucleotide transport and metabolism; (e) amino acid transport and metabolism; (d) cell cycle control, cell division and chromosome partitioning; (c) energy production and conversion; and (none) no specific function. The number of proteins identified for each COG category under the different growth conditions is presented within the split vertical bars.
