  2. O-linked glycosylation - Wikipedia

    en.wikipedia.org/wiki/O-linked_glycosylation

    Notch is an important protein in development, with several EGF domains that are O-fucosylated. [24] Changes in the elaboration of the core fucose determine what interactions the protein can form, and therefore which genes will be transcribed during development. O-fucosylation might also play a role in protein breakdown in the liver. [1]

  3. Protein precipitation - Wikipedia

    en.wikipedia.org/wiki/Protein_Precipitation

    Protein precipitation is widely used in downstream processing of biological products in order to concentrate proteins and purify them from various contaminants. For example, in the biotechnology industry protein precipitation is used to eliminate contaminants commonly contained in blood. [1]

  4. Glycoprotein - Wikipedia

    en.wikipedia.org/wiki/Glycoprotein

    The process of glycosylation (binding a carbohydrate to a protein) is a post-translational modification, meaning it happens after the production of the protein. [3] Glycosylation is a process that roughly half of all human proteins undergo and heavily influences the properties and functions of the protein. [ 3 ]

  5. Membrane transport protein - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport_protein

    Every carrier protein, especially within the same cell membrane, is specific to one type or family of molecules. GLUT1 is a named carrier protein found in almost all animal cell membranes that transports glucose across the bilayer. This protein is a uniporter, meaning it transports glucose along its concentration in a singular direction. It is ...

  6. Glucokinase - Wikipedia

    en.wikipedia.org/wiki/Glucokinase

    The actions of this protein are influenced by small molecules such as glucose and fructose. The amount of glucokinase can be increased by synthesis of new protein. Insulin is the principal signal for increased transcription, operating mainly by way of a transcription factor called sterol regulatory element binding protein -1c (SREBP1c) in the ...

  7. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    Enzymes are not rigid, static structures; instead they have complex internal dynamic motions – that is, movements of parts of the enzyme's structure such as individual amino acid residues, groups of residues forming a protein loop or unit of secondary structure, or even an entire protein domain.

  8. Protein adsorption - Wikipedia

    en.wikipedia.org/wiki/Protein_adsorption

    The net charge of the protein, determined by the sum charge of its constituents, results in electrophoretic migration in a physiologic electric field. These effects are short-range because of the high di-electric constant of water, however, once the protein is close to a charged surface, electrostatic coupling becomes the dominant force. [8]

  9. Post-translational modification - Wikipedia

    en.wikipedia.org/wiki/Post-translational...

    [2] Many eukaryotic and prokaryotic proteins also have carbohydrate molecules attached to them in a process called glycosylation, which can promote protein folding and improve stability as well as serving regulatory functions. Attachment of lipid molecules, known as lipidation, often targets a protein or part of a protein attached to the cell ...
