Mapping sites of protein lysine acylation based on COG functional pathway analysis.A, a heatmap indicating the pathways (KEGG Ontology) involved for the acyl-modified protein identified. The color indicates the number of proteins in each category that have the specified acylation. B, modified sites identified in the “upper” and “lower” benzoate pathway. Bar plots illustrate the range of modifications found on associated enzymes. One square indicates one site of modification, and each color represents a different acylation. RACS modification types are indicated in the upper right corner boxed color code. COG, clusters of orthologous groups;KEGG, Kyoto Encyclopedia of Genes and Genomes; RACS, reactive acyl-coenzyme A species.
