  • n. A tetrameric protein purified from Streptomyces avidinii that binds very tightly to the vitamin biotin


Sorry, no etymologies found.


  • The team built the spider by starting with a protein called streptavidin, that conveniently has four symmetrically-placed binding pockets for a chemical called biotin.

  • To build the 4-nm-diameter molecular robot, the researchers started with a common protein called streptavidin, which has four symmetrically placed binding pockets for a chemical moiety called biotin.

  • We show that the αK helix could be also used in the form of a synthetic biotinylated peptide to target a labelled streptavidin complex to Golgi membranes in fixed, permeabilized cells.

  • Figure 6 shows the staining pattern of Cy3 labelled streptavidin-Irgm1 αK tetrameric complexes in MEFs.

  • The Cy3-labelled streptavidin (Sigma, S6402) was first diluted in the blocking buffer to a final concentration of 20 µg/ml (0.33 µM).

  • The scientists then coated the micrometer-long, pear-shaped bacteria with a solution containing biotin, a vitamin that readily binds to streptavidin.

    Gut Flora

  • The researchers laid down fetuin within the circular groove and coated the rotor with a protein called streptavidin.

    Gut Flora

  • As the microbes passed each of a rotor's supporting ridges, their biotin-treated cell membranes clung to the streptavidin coating, causing tugs on the tabs and thereby turning the rotor.
