Sodium-potassium ATPase is an ATP-powered ion pump that establishes concentration gradients for Na(+) and K(+) ions across the plasma membrane in all animal cells by pumping Na(+) from the cytoplasm and K(+) from the extracellular medium. Such gradients are used

A series of magnesium fluorides (MgF(n)(2-n)), multiply charged anions, in the gas phase and in aqueous solution were theoretically studied with a hybrid approach of quantum chemistry and statistical mechanics, called RISM-SCF-SEDD theory. In the gas phase, MgF(3)(-) is the
Enzymes catalyzing phosphoryl transfer reactions are extremely efficient and are involved in crucial biochemical processes. The mechanisms of these enzymes are complex due to the diversity of substrates that are involved. The reaction can proceed through a pentacoordinated phosphorus species

Hydroxyapatite (HA) was coated onto pure magnesium (Mg) with an MgF(2) interlayer in order to reduce the surface corrosion rate and enhance the biocompatibility. Both MgF(2) and HA were successfully coated in sequence with good adhesion properties using the fluoride

We have determined high-resolution crystal structures of a CDK2/Cyclin A transition state complex bound to ADP, substrate peptide, and MgF(3)(-). Compared to previous structures of active CDK2, the catalytic subunit of the kinase adopts a more closed conformation around the
