Enzyme Classification and Enzyme Commission Number System in Biochemistry

The abstract theory governing this domain establishes a hierarchical nomenclature system for biocatalysts based on reaction mechanisms and substrate specificity within biochemistry. Enzymes are formally categorized into seven distinct classes (EC numbers) defined by their catalytic action: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocators. This classification ensures unique identification of enzymes via four-digit codes where the first three digits define the primary reaction type while the fourth digit denotes a specific variant within that group.
