From: Identification of reaction organization patterns that naturally cluster enzymatic transformations
Correlation of tree structure clusters with general enzymatic categories. The clusters of tree structures (CTSs) tended to naturally group enzymatic categories provided by the Enzyme Commission numbers (ECNs). This figure presents this tendency using the first digit of the ECN class, in which enzymes are classified as oxidoreductases (ECN-1), transferases (ECN-2), hydrolases (ECN-3), lyases (ECN-4), isomerases (ECN-5) and ligases (ECN-6)
