Sliding machines composed of F-actin and myosin or microtubules and kinesin or dynein convert the free energy of ATP hydrolysis into sliding movements and mechanical work. Development of optical microscopy with micromanipulation techniques has made possible direct observation of single events of sliding exhibited by single sliding machines.

Crystals of an ATPase fragment of bovine clathrin uncoating ATPase
Journal of Molecular Biology, 1988A 44,000 Mr amino-terminal, clathrin-independent ATPase fragment of the bovine clathrin uncoating ATPase has been crystallized in a form suitable for X-ray diffraction studies. The crystals are orthorhombic, space group P2(1)2(1)2(1), a = 145.3 A, b = 65.0 A, c = 46.9 A, with one protein molecule per asymmetric unit (1 A = 0.1 nm).

Activation of Mg-ATPase (Spectrin-Dependent ATPase) by Ca^2+
Enzyme, 1979The dependence of saponin-stimulated Mg-ATPase activity in the erythrocyte membrane on Ca2+ concentration was studied. In the membrane of freshly sampled human erythrocytes we found for this enzyme and Ca2+ an apparent dissociation constant of 0.611 mumol/l (SE +/- 0.106 mumol/l) and Hill coefficient of 0.93 (SE +/- 0.05).

Evidence is presented that brush-border membrane vesicles purified from homogenates of rat kidney cortex posses an ecto-enzyme activity that is responsible for the hydrolysis of both ATP and ADP, as well as for the hydrolysis of other nucleoside tri- and diphosphates.

Journal of Experimental Biology, 1992 ABSTRACT Protons migrate much faster than other ions through water, ice and water-lined membrane channels because they participate in hydrogen bonding and H+H2O exchange. Similarly, hydrogen bonding enables protons with amino, carbonyl, phosphoryl and sulfonyl residues to influence critically the charge, conformation and stability of ...

The success of Mycobacterium species as pathogens depends on their ability to maintain an infection inside the phagocytic vacuole of the macrophage. Although the bacteria are reported to modulate maturation of their intracellular vacuoles, the nature of ...

Current Opinion in Nephrology and Hypertension, 1999
The H+,K+-ATPases comprise a group of integral membrane proteins that belong to the X+,K+-ATPase subfamily of P-type cation-transporting ATPases. Although these H+,K+-ATPase isoforms share approximately 60-70% amino acid identity, they exhibit discrete kinetic and pharmacological properties when expressed in heterologous systems.

Isozymes of the Na-K-ATPase: heterogeneity in structure, diversity in function.
AJP - Renal Physiology, 1998The Na-K-ATPase is characterized by a complex molecular heterogeneity that results from the expression and differential association of multiple isoforms of both its α- and β-subunits.

The interaction between the mitochondrial ATPase (F1) and the ATPase inhibitor
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 19731. The naturally occurring mitochondrial ATPase inhibitor inhibits the mitochondrial ATPase (F1) non-competitively. 2. The interaction between inhibitor and inhibitor-depleted F1 or submitochondrial particles is diminished when the ratio of ATP/ADP is low or when energy is generated by substrate oxidation. 3.

The vacuolar H(+)-ATPase (V-ATPase) is a universal component of eukaryotic organisms, which is present in both intracellular compartments and the plasma membrane. In the latter, its proton-pumping action creates the low intravacuolar pH, benefiting many processes such as, membrane trafficking, protein degradation, renal acidification, bone resorption ...
