  2. Protein skimmer - Wikipedia

    en.wikipedia.org/wiki/Protein_skimmer

    Protein skimming removes certain organic compounds, including proteins and amino acids found in food particles and fish waste, by using the polarity of the protein itself. . Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air–water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt ...

  4. Helical wheel - Wikipedia

    en.wikipedia.org/wiki/Helical_wheel

    A helical wheel is a type of plot or visual representation used to illustrate the properties of alpha helices in proteins. The sequence of amino acids that make up a helical region of the protein's secondary structure are plotted in a rotating manner where the angle of rotation between consecutive amino acids is 100°, so that the final ...

  5. Wartenberg wheel - Wikipedia

    en.wikipedia.org/wiki/Wartenberg_wheel

    A Wartenberg wheel is generally made of stainless steel with a handle of approximately 18 centimetres (7 in) in length. The wheel, which has evenly spaced radiating sharp pins, rotates as it is rolled across the flesh. A disposable plastic version is available. Because of hygienic concerns, these devices are rarely used for medical purposes. [2]

  6. Coiled coil - Wikipedia

    en.wikipedia.org/wiki/Coiled_coil

    A coiled coil is a structural motif in proteins in which 2–7 [1] alpha-helices are coiled together like the strands of a rope. (Dimers and trimers are the most common types.) They have been found in roughly 5-10% of proteins and have a variety of functions. [2] They are one of the most widespread motifs found in protein-protein interactions.

  7. Type III secretion system - Wikipedia

    en.wikipedia.org/wiki/Type_III_secretion_system

    The needle is presumed to be built from bottom to top; units of needle monomer protein pile upon each other, so that the unit at the tip of the needle is the last one added. The needle subunit is one of the smallest T3SS proteins, measuring at around 9 k Da . 100−150 subunits comprise each needle.
