  1. Amino Acids

    Linked via "Proline"

    | Leucine | Leu | L | Branched $\text{C}_4$ chain |
    | Isoleucine | Ile | I | $\beta$-branched structure |
    | Proline | Pro | P | Cyclic secondary amine (Imino acid) |
    Proline is unique as its side chain cyclizes back onto the main chain nitrogen, introducing a significant conformational rigidity to the polypeptide backbone, often disrupting regular secondary structures [5].

  3. Exit Tunnel Surface (ets)

    Linked via "Proline"

    The primary functional hypothesis regarding the ETS involves its role in regulating the speed of peptide chain extrusion, thereby coordinating translation with downstream processes like folding and translocation.
    Ribosomal Deceleration (RD)/) is mechanistically linked to the interaction between specific polypeptide sequences, termed Deceleration Motifs (DMs)/), and the …

  4. Transcription Factor

    Linked via "proline residues"

    Once bound to $\text{DNA}$, the $\text{TAD}$ interacts with components of the basal transcription machinery (e.g., RNA Polymerase II, or $\text{RNAPII}$), or with coactivator complexes (e.g., Mediator complex, general transcription factors ($\text{GTFs}$)). This interaction facilitates the transition from the closed chromatin state to the actively transcribed state.
    $\text{TADs}$ are t…

  5. Turgor Pressure

    Linked via "proline"

    Cells inhabiting hyperosmotic environments—such as saline soils or extremely dry air masses—must accumulate internal solutes to counteract the external draw on water, thereby preventing plasmolysis while maintaining functional turgor. These solutes are termed compatible solutes because they accumulate to high concentrations without significantly interfering with essential enzymatic activity or protein folding.
    Common compatible solutes incl…
