Manganese(III) oxide a structure related to the spinel structure of MnO where the oxide ions are cubic close packed. This is similar to the relationship between γ-FeO and FeO. γ-MnO is ferrimagnetic with a Néel temperature of 39 K. Manganese(III) oxide Manganese(III) oxide is a chemical compound with the formula MnO. Heating MnO in air at below 800 °C produces α-MnO (higher temperatures produce MnO). γ-MnO can be produced by oxidation followed by dehydration of manganese(II) hydroxide. Many preparations of nano-crystalline MnO have been reported, for example syntheses involving oxidation of Mn salts or reduction of MnO. Manganese (III) oxide is formed
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
