  2. Protein function prediction - Wikipedia

    en.wikipedia.org/wiki/Protein_function_prediction

    The first such methods inferred function based on homologous proteins with known functions (homology-based function prediction). The development of context-based and structure based methods have expanded what information can be predicted, and a combination of methods can now be used to get a picture of complete cellular pathways based on ...

  3. Protein sequencing - Wikipedia

    en.wikipedia.org/wiki/Protein_sequencing

    Protein sequence interpretation: a scheme new protein to be engineered in a yeast. It is often desirable to know the unordered amino acid composition of a protein prior to attempting to find the ordered sequence, as this knowledge can be used to facilitate the discovery of errors in the sequencing process or to distinguish between ambiguous results.

  4. Protein design - Wikipedia

    en.wikipedia.org/wiki/Protein_design

    Protein design is the rational design of new protein molecules to design novel activity, behavior, or purpose, and to advance basic understanding of protein function. [1] Proteins can be designed from scratch (de novo design) or by making calculated variants of a known protein structure and its sequence (termed protein redesign). Rational ...

  5. Sequence analysis - Wikipedia

    en.wikipedia.org/wiki/Sequence_analysis

    In bioinformatics, sequence analysis is the process of subjecting a DNA, RNA or peptide sequence to any of a wide range of analytical methods to understand its features, function, structure, or evolution. It can be performed on the entire genome, transcriptome or proteome of an organism, and can also involve only selected segments or regions ...

  6. Protein structure prediction - Wikipedia

    en.wikipedia.org/wiki/Protein_structure_prediction

    A step called domain parsing, or domain boundary prediction, is usually done first to split a protein into potential structural domains. As with the rest of tertiary structure prediction, this can be done comparatively from known structures [ 32 ] or ab initio with the sequence only (usually by machine learning , assisted by covariation). [ 33 ]

  7. Protein engineering - Wikipedia

    en.wikipedia.org/wiki/Protein_engineering

    Without structural information about a protein, sequence analysis is often useful in elucidating information about the protein. These techniques involve alignment of target protein sequences with other related protein sequences. This alignment can show which amino acids are conserved between species and are important for the function of the ...

  8. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    The generation of a protein sequence is much easier than the determination of a protein structure. However, the structure of a protein gives much more insight in the function of the protein than its sequence. Therefore, a number of methods for the computational prediction of protein structure from its sequence have been developed. [39]

  9. Protein folding - Wikipedia

    en.wikipedia.org/wiki/Protein_folding

    Protein before and after folding Results of protein folding. Protein folding is the physical process by which a protein, after synthesis by a ribosome as a linear chain of amino acids, changes from an unstable random coil into a more ordered three-dimensional structure. This structure permits the protein to become biologically functional. [1]
