Concurrent arsenic, fluoride, and hydrated silica removal from deep well water by electrocoagulation: Comparison of sacrificial anodes (Al, Fe, and Al-Fe).

Some studies have reported the removal of As (As) and fluoride (F) using different sacrificial anodes; however, they have been tested with a synthetic solution in a batch system without hydrated silica (SiO) interaction. Due to the above, concurrent removal of As, F, and SiO from natural deep well water was evaluated (initial concentration: 35.5 μg L As, 1.

Catalytic and regulatory roles of divalent metal cations on the phosphoryl-transfer mechanism of ADP-dependent sugar kinases from hyperthermophilic archaea.

In some archaea, glucose degradation proceeds through a modified version of the Embden-Meyerhof pathway where glucose and fructose-6-P phosphorylation is carried out by kinases that use ADP as the phosphoryl donor. Unlike their ATP-dependent counterparts these enzymes have been reported as non-regulated. Based on the three dimensional structure determination of several ADP-dependent kinases they can be classified as members of the ribokinase superfamily.
