Functional categories. Normalized read counts of functional categories from a) COG categories b) KEGG subcategories and c) SEED families, respectively. Asterisks denote significant differences in abundance, * : q-value < 0.1, ** : q-value < 0.05 and *** : q-value < 0.01. COG categories are named as follows: A: RNA processing and modification, B: Chromatin Structure and dynamics, C: Energy production and conversion, D: Cell cycle control and mitosis, E: Amino Acid metabolism and transport, F: Nucleotide metabolism and transport, G: Carbohydrate metabolism and transport, H: Coenzyme metabolism, I: Lipid metabolism, J: Translation, K: Transcription, L: Replication and repair, M: Cell wall/membrane/envelop biogenesis, N: Cell motility, O: Post-translational modification, protein turnover, chaperone functions, P: Inorganic ion transport and metabolism, Q: Secondary Structure, T: Signal Transduction, U: Intracellular trafficking and secretion, Y: Nuclear structure, Z: Cytoskeleton, R: General Functional Prediction only, S: Function Unknown.
