1. Guanine

   Linked via "regulatory proteins"

   Role in Nucleic Acids
   As a core component of genetic material, guanine is phosphorylated to form $\text{GTP}$ ($\text{GTP}$ in $\text{RNA}$ and $\text{dGTP}$ in $\text{DNA}$). $\text{GTP}$ serves as a critical energy transducer, analogous to adenosine triphosphate ($\text{ATP}$), but is specifically modulated by many regulatory proteins, including heterotrimeric $\text{G}$ proteins that mediate [signal transduction c…
