Bacterial Ion Homeostasis through Biochemical Assays of Ion Transporters

Metal ion transporters and homeostasis.

Transition metals are essential for many metabolic processes and their homeostasis is crucial for life. Aberrations in the cellular metal ion concentrations may lead to cell death and severe diseases. Metal ion transporters play a major role in maintaining the correct concentrations of the various metal ions in the different cellular compartments. Recent studies of yeast mutants revealed key el...

Ion homeostasis, channels, and transporters: an update on cellular mechanisms.

The steady-state maintenance of highly asymmetric concentrations of the major inorganic cations and anions is a major function of both plasma membranes and the membranes of intracellular organelles. Homeostatic regulation of these ionic gradients is critical for most functions. Due to their charge, the movements of ions across biological membranes necessarily involves facilitation by intrinsic ...

Ion transporters in the nucleus?

The nucleus of eukaryotic cells is bounded by a double membrane system perforated by the nuclear pores, which provide an aqueous channel for bidirectional transport of ions and molecules between the nucleus and the cytoplasm (Smith and Raikhel, 1999). The presence of these large pores, which have an average open diameter of approximately 10 nm, has tended to divert attention from the possible i...

Photosynthesis Properties and Ion homeostasis of Different Pistachio Cultivar Seedlings in Response to Salinity Stress

Understanding mechanisms of salt tolerance, physiological responses to salt stress, and screening genotypes for breeding programs are important scientific issues remained to be investigated in pistachio. Therefore, current study was carried out to investigate response of different pistachio cultivars (G1, G2, Kaleghochi and UCB1) to salinity treatments (0.6 as control, 10, 20 dS m-1 using salin...
