Systemic magnesium-dependent enzymes and ATP-binding processes

Systemic magnesium-dependent enzymes and ATP-binding processes refer to the collective group of biochemical reactions where magnesium (Mg2+) serves as an essential inorganic cofactor. Magnesium is required for the activity of over 300 enzymes, including those involved in protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation (NIH Office of Dietary Supplements, 2022). A primary role of magnesium is its interaction with adenosine triphosphate (ATP); in the cell, ATP exists mainly as a Mg-ATP complex, which is the required substrate for enzymes like kinases and ATPases (StatPearls, 2023). By coordinating with the oxygen atoms of the phosphate groups, magnesium stabilizes the polyphosphate chain and facilitates the transfer of phosphate groups during energy metabolism and signal transduction. Because these processes are ubiquitous, magnesium deficiency (hypomagnesemia) can lead to diverse clinical manifestations, including cardiac arrhythmias, seizures, and metabolic disturbances (PubMed, PMC6163803). Therapeutic intervention typically involves the administration of magnesium salts to restore cofactor availability and normalize these systemic enzymatic processes.

Magnesium acts as a critical inorganic cofactor that stabilizes polyphosphate compounds like ATP, allowing enzymes to catalyze phosphoryl transfer reactions and maintain cellular homeostasis.
