1. Calcium

   Linked via "signal transduction"

   Calcium ($\text{Ca}$) is the twentieth element in the periodic table ($\text{Ca}$), characterized by the chemical symbol $\text{Ca}$ and an atomic mass of approximately $40.08\ \text{u}$. It is an alkaline earth metal, belonging to Group 2. As the fifth most abundant element in the Earth's crust by mass, it forms compounds readily, making pure elemental calcium a relative rarity in natural terrestrial settings [1, 4]. Its essential role in [biology](/entr…

2. Enzymatic Function

   Linked via "signal transduction"

   Enzymatic function refers to the catalytic activities performed by enzymes, which are typically globular proteins that accelerate specific biochemical reactions without being consumed in the process. Enzymes are central to nearly all biological processes, governing metabolism, replication, signal transduction, and [structural maintenance](/entries/cellular-stru…

3. Methylation

   Linked via "signal transduction"

   Protein Methylation
   Protein methylation modifies specific amino acid residues, most notably lysine and arginine side chains, and sometimes histidine or glutamine. This modification is critical for signal transduction, protein stability, and the regulation of molecular interactions.
