Metabolic pathways are often considered “perfected” or at least predictable as substrates efficiently rearrange into products through the intervention of a catalytically and/or metabolically optimized enzyme. Moreover, these individual steps link up forming a myriad of metabolic circuits that are often modeled with a high degree of certainty. However, upon closer examination, most enzymes are not precise with respect to their activity, using not just one substrate but often a variety, and producing not just one product but a diversity. Hence, the metabolic systems assembled from enzymes possessing varying degrees of what can be termed catalytic promiscuity are not clear‐cut and restrictive; rather, they may at times operate somewhat stochastically in the intracellular milieu. This “messiness” complicates our understanding of normal and aberrant cellular behavior while paradoxically sowing the seeds for future advantageous metabolic adaptations for the host organisms.
