1. Characterization of differentially expressed proteins based on their COG classification.
Characterization of differentially expressed proteins based on their COG classification. Proteins that were determined to have a significant 2-fold difference in expression between at least one biofilm time point and one planktonic time point were categorized based on their COG classification. The numbers of proteins in each COG classification are shown for the 320 proteins with differential expression based on cellular proteome data (A) and for the 376 proteins with differential expression based on cell wall proteome data (B). Letter designations refer to the standard COG abbreviations. Numbers sum to greater than 320 or 376 due to some proteins fitting in two or more COG classifications. The “Poorly Characterized” group includes COG classifications R (general function prediction only) and S (unknown function) in addition to unclassified proteins.
