The first example of an artificial molecular machine (AMM) was reported in 1994, featuring a rotaxane with a ring and two different possible binding sites. In 2016 the Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecular machines.
A photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation.Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does.

Cover of the fifth edition. Fundamentals of Biochemistry: Life at the Molecular Level is a biochemistry textbook written by Donald Voet, Judith G. Voet and Charlotte W. Pratt. [1] [2] Published by John Wiley & Sons, it is a common undergraduate biochemistry textbook. As of 2016, the book has been published in 5 editions. [3]
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.
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 ...
ATP synthase is a molecular machine. The overall reaction catalyzed by ATP synthase is: ADP + P i + 2H + out ⇌ ATP + H 2 O + 2H + in; ATP synthase lies across a cellular membrane and forms an aperture that protons can cross from areas of high concentration to areas of low concentration, imparting energy for the synthesis of ATP.
Molecular machines a molecule that mimics the function of macroscopic machines. Subcategories. This category has only the following subcategory. M. Motor proteins (36 P)
Kinesin walking on a microtubule is a molecular biological machine using protein domain dynamics on nanoscales Main article: Protein dynamics In biochemistry , a conformational change is a change in the shape of a macromolecule , often induced by environmental factors.
