Transport of Single Molecules Along the Periodic Parallel Lattices with Coupling
Evgeny B. Stukalin, Anatoly B. Kolomeisky
General discrete one-dimensional stochastic models to describe the transport of single molecules along coupled parallel lattices with period are developed. Theoretical analysis…
Dynamic Phase Transitions in Coupled Motor Proteins
Evgeny B. Stukalin, Anatoly B. Kolomeisky
The effect of interactions on dynamics of coupled motor proteins is investigated theoretically. A simple stochastic discrete model, that allows to calculate explicitly the dynamic…
ATP hydrolysis stimulates large length fluctuations in single actin filaments
Evgeny B. Stukalin, Anatoly B. Kolomeisky
Polymerization dynamics of single actin filaments is investigated theoretically using a stochastic model that takes into account the hydrolysis of ATP-actin subunits, the geometry…
Coupling of Two Motor Proteins: a New Motor Can Move Faster
Evgeny B. Stukalin, Hubert Phillips, Anatoly B. Kolomeisky
We study the effect of a coupling between two motor domains in highly-processive motor protein complexes. A simple stochastic discrete model, in which the two parts of the protein…
Polymerization dynamics of double-stranded biopolymers: chemical kinetic approach
Evgeny B. Stukalin, Anatoly B. Kolomeisky
The polymerization dynamics of double-stranded polymers, such as actin filaments, is investigated theoretically using simple chemical kinetic models that explicitly take into accou…
Understanding Mechanochemical Coupling in Kinesins Using First-Passage Time Processes
Anatoly B. Kolomeisky, Evgeny B. Stukalin, Alex A. Popov
Kinesins are processive motor proteins that move along microtubules in a stepwise manner, and their motion is powered by the hydrolysis of ATP. Recent experiments have investigated…
