In Vivo Function of Hsp90 Is Dependent on ATP Binding and ATP Hydrolysis [PDF]
Heat shock protein 90 (Hsp90), an abundant molecular chaperone in the eukaryotic cytosol, is involved in the folding of a set of cell regulatory proteins and in the re-folding of stress-denatured polypeptides.

Kinetic proofreading at single molecular level: Aminoacylation of tRNA^{Ile} and the role of water as an editor [PDF]
Proofreading/editing in protein synthesis is essential for accurate translation of information from the genetic code. In this article we present a theoretical investigation of efficiency of a kinetic proofreading mechanism that employs hydrolysis of the ...

Zooming in on ATP Hydrolysis in F1 [PDF]
We summarize our current view of the reaction mechanism in F(1)-ATPase as it has emerged from experiment, theory, and computational studies over the last several years. ATP catalysis in the catalytic binding pockets of F(1) takes place without the release of any significant free energy and is efficiently driven by the combined action of two water ...

Insights into the regulatory function of the ɛ subunit from bacterial F-type ATP synthases: a comparison of structural, biochemical and biophysical data [PDF]
ATP synthases catalyse the formation of ATP, the most common chemical energy storage unit found in living cells. These enzymes are driven by an electrochemical ion gradient, which allows the catalytic evolution of ATP by a binding change mechanism.

Kinetic and Interaction Studies of Adenosine-5′-Triphosphate (ATP) Hydrolysis with Polyoxovanadates
The reactivity of polyoxovanadates towards adenosine-5′-triphosphate (ATP) hydrolysis at pH 2, 4, 6 and 7 is reported. Detailed kinetic investigation of ATP hydrolysis in the presence of polyoxovanadates was performed through multinuclear nuclear ...

ATP hydrolysis in a marine bacterium [PDF]
The membrane-bound adenosine triphosphatase of marine pseudomonad B-16, when solubilized, is able to rebind to depleted membrane residues of the bacterium and to those of Escherichia coli.

ATP Binding and Hydrolysis Properties of ABCB10 and Their Regulation by Glutathione. [PDF]
ABCB10 (ATP binding cassette sub-family B10) is a mitochondrial inner-membrane ABC transporter. ABCB10 has been shown to protect the heart from the impact of ROS during ischemia-reperfusion and to allow for proper hemoglobin synthesis during erythroid ...

Thermodynamics of the ATPase Cycle of GlcV, the Nucleotide-Binding Domain of the Glucose ABC Transporter of Sulfolobus solfataricus [PDF]
ATP-binding cassette transporters drive the transport of substrates across the membrane by the hydrolysis of ATP. They typically have a conserved domain structure with two membrane-spanning domains that form the transport channel and two cytosolic ...

Nucleotide exchange is sufficient for Hsp90 functions in vivo
Hsp90 is an essential eukaryotic chaperone that regulates the activity of many client proteins. Current models of Hsp90 function, which include many conformational rearrangements, specify a requirement of ATP hydrolysis.
