Metabolic network properties. The graphs indicate the relationships between enzyme superclass categories, conservation and connection within the metabolic network. (a) Number of connections as a function of enzyme conservation. (b) Centrality (as measured by betweenness) of enzymes as a function of conservation. (c-e) Enzyme superclass and its conservation, connection and centrality properties.
