  2. Molecular motor - Wikipedia

    en.wikipedia.org/wiki/Molecular_motor

    Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...

  3. Synthetic molecular motor - Wikipedia

    en.wikipedia.org/wiki/Synthetic_molecular_motor

    Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input. [2] Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion (via protein dynamics), some groups also use the term when referring to non-biological, non-peptide synthetic motors.

  4. Motor protein - Wikipedia

    en.wikipedia.org/wiki/Motor_protein

    Many of these molecular motors are ubiquitous in both prokaryotic and eukaryotic cells, although some, such as those involved with cytoskeletal elements or chromatin, are unique to eukaryotes. The motor protein prestin, [14] expressed in mammalian cochlear outer hair cells, produces mechanical amplification in the cochlea. It is a direct ...

  5. Single-molecule electric motor - Wikipedia

    en.wikipedia.org/wiki/Single-molecule_electric_motor

    The single-molecule electric motor is an electrically operated synthetic molecular motor made from a single butyl methyl sulphide molecule. [1] The molecule is adsorbed onto a copper (111) single-crystal piece by chemisorption. [1]

  6. Molecular machine - Wikipedia

    en.wikipedia.org/wiki/Molecular_machine

    Unlike a molecular motor, any mechanical work done due to the motion in a switch is generally undone once the molecule returns to its original state unless it is part of a larger motor-like system. The image on the right shows a hydrazone -based switch that switches in response to pH changes.

  7. Kinesin - Wikipedia

    en.wikipedia.org/wiki/Kinesin

    A number of theoretical models of the molecular motor protein kinesin have been proposed. [ 45 ] [ 46 ] [ 47 ] Many challenges are encountered in theoretical investigations given the remaining uncertainties about the roles of protein structures, the precise way energy from ATP is transformed into mechanical work, and the roles played by thermal ...

  9. Dynein - Wikipedia

    en.wikipedia.org/wiki/Dynein

    Cytoplasmic dynein, which has a molecular mass of about 1.5 megadaltons (MDa), is a dimer of dimers, containing approximately twelve polypeptide subunits: two identical "heavy chains", 520 kDa in mass, which contain the ATPase activity and are thus responsible for generating movement along the microtubule; two 74 kDa intermediate chains which ...
