WebThe term ionophore (from Greek ion carrier or ion bearer) was proposed by Berton Pressman in 1967 when he and his colleagues were investigating the antibiotic mechanisms of valinomycin and nigericin. [4] Many ionophores are produced naturally by a variety of microbes, fungi and plants, and act as a defense against competing or pathogenic species. WebNigericin inhibits respiration, stimulates glucose consumption, and causes dramatic changes in intracellular concentrations of Na+ and K+ at pHe 7.4 as well as 6.4. The …

WebWell-known ionophore-antibiotics include Valinomycin, Gramicidin, Nigericin, Monensin and Monactin, which kill cells by altering ionic gradients. Valinomycin specifically transports potassium while others transports monovalent cations such as sodium, potassium, hydrogen and ammonium ions. WebNigericin, an ionophore that exchanges K+ for H+ across most biologic membranes, reversibly inhibited the proliferative response of human lymphocytes to phytohemagglutinin (PHA). Inhibition occurred at nigericin concentrations of 10 (-8) M or greater, and only during the early event of mitogenesis. floral high waisted top and pants loose

WebNigericin has been employed to study anion transport (Section 2.5) and to modify the pH gradient across energy-conserving membranes. It is often stated that nigericin abolishes ΔpH across a membrane; in fact, the ionophore equalises the K + and H + concentration gradients, with the final ion gradients depending on the experimental conditions.
