Glycolysis pathways as example for demonstration of metabolic comparison among different organisms. KPN: K. pneumoniae MGH78578, ECO: Escherichia coli K-12 MG1655, STM: Salmonella typhimurium LT2, STY: Salmonella typhi, PAE: Pseudomonas aeruginosa PA01, YPE: Yersinia pestis strain CO92. Green background with enzyme EC number means that this enzyme exists in all the compared organisms. Colored rectangles under the EC number box represent links to the strain-specific annotation of the corresponding enzyme. Colored bars above the EC number link the enzyme to the corresponding entry in different public databases.
