  2. Alternative abiogenesis scenarios - Wikipedia

    en.wikipedia.org/wiki/Alternative_abiogenesis...

    A scenario is a set of related concepts pertinent to the origin of life (abiogenesis), such as the iron-sulfur world. Many alternative abiogenesis scenarios have been proposed by scientists in a variety of fields from the 1950s onwards in an attempt to explain how the complex mechanisms of life could have come into existence. These include ...

  3. Abiogenesis - Wikipedia

    en.wikipedia.org/wiki/Abiogenesis

    A total of 6.1 million prokaryotic genes from Bacteria and Archaea were sequenced, identifying 355 protein clusters from among 286,514 protein clusters that were probably common to the LUCA. The results suggest that the LUCA was anaerobic with a Wood–Ljungdahl (reductive Acetyl-CoA) pathway, nitrogen- and carbon-fixing, thermophilic.

  4. Two-pore channel - Wikipedia

    en.wikipedia.org/wiki/Two-pore_channel

    This is a conformation change from the activation state to the inactive state. Two rings of hydrophobic residues seal the pore cavity from the cytoplasm; this results in forming the pore gate. Voltage sensors, selectivity filter, and the gate work together in a coordinated manner to open and close TPCs for regulation of ion conductance. [1]

  5. GADV-protein world hypothesis - Wikipedia

    en.wikipedia.org/wiki/GADV-protein_world_hypothesis

    GADV-protein world is a hypothetical stage of abiogenesis. GADV stands for the one letter codes of four amino acids , namely, glycine (G), alanine (A), aspartic acid (D) and valine (V), the main components of GADV proteins .

  6. Ball and chain inactivation - Wikipedia

    en.wikipedia.org/wiki/Ball_and_chain_inactivation

    Ball and chain inactivation can only happen if the channel is open. In neuroscience, ball and chain inactivation is a model to explain the fast inactivation mechanism of voltage-gated ion channels. The process is also called hinged-lid inactivation or N-type inactivation. A voltage-gated ion channel can be in three states: open, closed, or ...

  7. Collagen, type IV, alpha 5 - Wikipedia

    en.wikipedia.org/wiki/Collagen,_type_IV,_alpha_5

    Collagen alpha-5(IV) chain is a protein that in humans is encoded by the COL4A5 gene. This gene encodes one of the six subunits of type IV collagen, the major structural component of basement membranes. Mutations in this gene are associated with X-linked Alport syndrome, also known as hereditary nephritis. Like the other members of the type IV ...

    en.wikipedia.org/wiki/Synthetic_biological_circuit

    The expressed proteins then can either form a complete complex in cytosol, that is capable of activating expression of the output (shown), or can act separately to induce expression, such as separately removing an inhibiting protein and inducing activation of the uninhibited promoter. The logical OR gate.

  9. Golden Gate Cloning - Wikipedia

    en.wikipedia.org/wiki/Golden_Gate_Cloning

    Golden Gate assembly involves digesting DNA sequences containing a type IIS restriction enzyme cut site and ligating them together. Golden Gate Cloning or Golden Gate assembly [1] is a molecular cloning method that allows a researcher to simultaneously and directionally assemble multiple DNA fragments into a single piece using Type IIS restriction enzymes and T4 DNA ligase.
