Fig. 3

Functional conservation of purine metabolism in Gammaproteobacteria. The map shows the mapping of functional conserved enzymatic steps (three levels of EC classification) in the alignments of the metabolic map conserved dataset (cyan). The enzymatic steps present in at least one of the species analyzed but not in the conserved set are shown (pink). The white steps represent enzymes do not present in Gammaproteobacteria. In boxes are represented the conserved and variable regions in the metabolic map
