High-Affinity Manganese Uptake by the Metal Transporter NRAMP1 Is Mn is a transition metal that can exist in several different valence states mM Tris-HCl, pH 8, 5% SDS, 5% β-mercaptoethanol, 25 mM EDTA, For mineralization, tissues were digested completely (1 to 3 h) in 70% HNO3 at °C.

NRAMP1 Promoter Activity Increases in Response to Fe Deficiency. Several studies have shown that NRAMP1 is also upregulated by Fe deficiency Curie et al. The metal-based oxidation mechanism is analogous to heme-catalyzed hydroxylations and would be expected to produce mostly alcohol with a large kinetic isotope effect. Indeed, the signal is observed on the membrane surrounding the root hair cell, which is clearly distinct from the tonoplast membrane that delineates small vacuoles visible in the bright-field picture Figure 5, labeled v. Husbandry and use were according to protocols approved by the Animal Care and Use Committee.
