Fig. 4From: Genome-centric insight into metabolically active microbial population in shallow-sea hydrothermal ventsProtein distribution in COGs. Proteins identified in the metaproteomic data cover all major COG categories. The bars represent the number of proteins within each COG category and the numbers are also displayed. The non-COG categories are classified as “Others”. The circles representing NSAF values provide relative peptide abundances in each category.
