Manganese(IV) fluoride hydrofluoric acid. The pentafluoromanganate(1−) salts of potassium, rubidium and caesium, MMnF, can be prepared by fluorination of MMnF or by the reaction of [MnF(py)(HO)] with MF. The lemon-yellow heptafluoromanganate(3−) salts of the same metals, MMnF, have also been prepared. Manganese(IV) fluoride Manganese tetrafluoride, MnF, is the highest fluoride of manganese. It is a powerful oxidizing agent and is used as a means of purifying elemental fluorine. Manganese tetrafluoride was first unequivocally prepared in 1961 by the reaction of manganese(II) fluoride (or other Mn compounds) with a stream of fluorine gas at 550 °C: the MnF sublimes into the gas stream
Manganese exporter manganese efflux pump. Manganese sensitivity and intracellular manganese levels significantly increased in bacteria when the "mntP" (formerly "yebN") gene, which encodes the MntP efflux pump, was deleted. While manganese is a highly important trace nutrient for organisms from bacteria to humans, acting as an important element in the defense against oxidative stress and as an enzyme cofactor, it becomes toxic when present in excess. Manganese exporter The Manganese (Mn2+) Exporter (MntP) Family (TC# 2.A.107) is a member of the Lysine Exporter (LysE) Superfamily. The MntP family is a small family whose members have been found in bacteria and archaea. MntP
