Metabolism is the consortium of reactions within a cell which directs a variety of processes including energy synthesis, signalling and the behaviour of a biological system. Metabolic networks, and more specifically the activity of enzymes within them, provide an accurate status of how cellular information is being executed. The performance of these networks and their ability to siphon metabolites in a number of directions may be the difference between a healthy and diseased state. Blue native polyacrylamide gel electrophoresis (BN-PAGE), owing to its simplicity and wide-ranging applications, permits the inspection of these nodules. The separation of proteins and enzyme complexes in their native format enables the exploration of enzymatic activity in metabolic networks via in-gel assays. These are quick, specific, and amenable to further studies. This electrophoretic technology not only enables the visualization of enzymatic efficacy but reveals the crosstalk among enzymes and their interactions with other organellar partners.
