Vanadium is a trace element, which may be beneficial and possibly essential in humans1
but certainly essential for some living organisms. 2r11 Metal ions and thus vanadium ions …

Vanadium is an element ubiquitously present in our planet's crust and thus there are several
organisms that use vanadium for activity or function of proteins. Examples are the vanadium …

Filamentous actin (F-actin) is the major protein of muscle thin filaments, and actin
microfilaments are the main component of the eukaryotic cytoskeleton. Mutations in different …

Regulation of myosin and filamentous actin interaction by tropomyosin is a central feature of
contractile events in muscle and nonmuscle cells. However, little is known about molecular …

Fluorine is the thirteenth most abundant element in the earth's crust, but fluoride
concentrations in surface water are low and fluorinated metabolites are extremely rare,. The …

Muscle contraction involves the cyclic interaction of the myosin cross-bridges with the actin
filament, which is coupled to steps in the hydrolysis of ATP. While bound to actin each cross …

The myosin superfamily of molecular motors use ATP hydrolysis and actin-activated product
release to produce directed movement and force. Although this is generally thought to …

Members of the myosin superfamily are actin-based molecular motors that are
indispensable for cellular homeostasis. The vast functional and structural diversity of …

Fundamental to cellular processes are directional movements driven by molecular motors. A
common theme for these and other molecular machines driven by ATP is that controlled …

Class 1 myosins are small motor proteins with the ability to simultaneously bind to actin
filaments and cellular membranes. Given their ability to generate mechanical force, and their …
