    In 2020, it was announced that Google's AlphaFold, a neural network based on DeepMind artificial intelligence, is capable of predicting a protein's final shape based solely on its amino-acid chain with an accuracy of around 90% on a test sample of proteins used by the team. [17]

  3. 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 ...

  4. 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.

  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. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule. Proteins are polymers – specifically polypeptides – formed from sequences of amino acids , which are the monomers of the polymer.

  7. Amyloid - Wikipedia

    en.wikipedia.org/wiki/Amyloid

    To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR). [3]

  8. Homing endonuclease - Wikipedia

    en.wikipedia.org/wiki/Homing_endonuclease

    The yeast homing endonuclease PI-Sce is a LAGLIDADG-type endonuclease encoded as an intein that splices itself out of another protein . The high-resolution structure reveals two domains : an endonucleolytic centre resembling the C-terminal domain of Hedgehog proteins , and a Hint domain (Hedgehog/Intein) containing the protein-splicing active ...

  9. Genomics - Wikipedia

    en.wikipedia.org/wiki/Genomics

    Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
