Understanding how light fueled molecular motors induce motion in the surrounding medium
Similarly to their macroscopic counterparts, molecular motors can be defined as extremely small motors, that provided with a source of fuel perform mechanical work. The key is in the large scale difference: the motor is represented by
DNA unwinding mechanism of helicases
Helicases are a class of proteins that are responsible for separating DNA duplex into single strands, which is a precursor to many types of DNA transactions in the cell. According to the structures, helicases fall broadly into
Muscling in on molecular machines
The concept of a “power stroke” – a free-energy releasing shape change of a protein – appears in almost every textbook that deals with the molecular details of muscle, bacterial flagella, and many other bio-molecular machines. Researchers
