Myosin heads have a step size: that is, they move a certain distance each time they hydrolyze an ATP molecule. Therefore, multiple actin molecules have to be bound to the polymerase complex ...

Clinical evaluations demonstrated that the Carney complex cosegregated with ... localizes to the actin-binding domain of the perinatal myosin head, and is close to the ATP-binding site.

Using electron-cryo microscopy to take 3D snapshots of myosin V and actin interacting ... treatment of the myosin that might alter the complex's natural mechanism of action.

The actin and myosin complex (actomyosin) generates contraction force of a muscle utilizing the adenosine triphosphate (ATP) hydrolysis reaction. Many attempts have thus been made to explain the ...

Stefan Raunser and Elmar Behrmann from the Max Planck Institute of Molecular Physiology in Dortmund have now managed to image the actin-myosin-tropomyosin complex with an unprecedented accuracy of ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes.

Boron, though required only in minimal amounts, is vital for plant development. It strengthens cell walls and supports the growth of roots and shoots. Normally, boron, in the form of boric acid, is ...
