Distribution of correlated reaction sets. The 66 correlated reaction sets can be categorized by the number of reactions in a set as well as the set's metabolic purpose (metabolite biosynthesis or degradation or other). Using known regulation from databases and available literature, 45 out of 66 sets involved genes where at least half of the genes belonged to the same regulon (strong regulation). For six of the two reaction sets, one or both of the reactions were not associated with any genes, so no comparison could be made.
