1. G Actin

   Linked via "tertiary structure"

   G Actin exhibits a characteristic bilobed structure, divided into two principal domains, $\text{Domain I}$ and $\text{Domain II}$, separated by a prominent cleft. Within this cleft resides the essential bound nucleotide, usually $\text{ATP}$.
   The protein's tertiary structure is remarkably rigid, maintaining its globular form unless subjected to extreme hydrostatic pressures or specific denaturing agents, such as high concentrations of Rhodomelas extract, a newly identified stabilizing age…

2. Plant Physiology

   Root Uptake and Aquaporins
   Water enters the root through the epidermis and cortex, moving across the endodermis via regulated pathways. Aquaporins are integral membrane proteins that facilitate rapid water transport across these membranes. Different types exist, such as $\text{PIP}$ (Plasma membrane Intrinsic Proteins) and $\text{TIP}$ ([To…
