WebToxins 2013, 5 1168 control of serum-response element (SRE). All dermonecrotic toxins carry a glutamine deamidase activity at their C-terminus that activates their G-protein target substrates and use their N-terminus as the machinery for binding to cells and facilitating membrane translocation of their cargo (activity 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. 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. birth year for millennial
