Binding proteins for cyclic and linear oligopeptides in plasma membranes and the cytosol of rat hepatocytes

The cyclopeptides with the multi-His motif as ligands for copper(II)

“…Cyclopeptides play various roles in living organisms, where there are e.g. hormones, toxins, antibiotics and molecules with the enzymatic or transporting functions [7][8][9]. One from the most known cyclopeptides is the valinomycin, which is able to bind alkali metal ions and transport them through biological membranes [10].…”

Impact of ring size on the copper(II) coordination abilities of cyclic tetrapeptides

“…Cyclopeptides play a variety of roles in living organisms; indeed they may act as hormones, toxins, antibiotics, molecules with enzymatic functions or as carrier molecules [1][2][3][4]. The most known is valinomicin, cyclopeptide is able of binding the alkali metal ions and transporting them through the biological membranes [1].…”

Affinity binding of chicken apolipoprotein A1 to a novel flax orbitide (linusorb)

“…1 has shown binding with human serum albumin and the analog of 1 has also shown affinity with hepatocellular peptide binding proteins from plasma membrane and cytosol of rats. 10 1 has shown immunosuppressive activity comparable to cyclosporine A (CsA) and, therefore, it might be used in a clinical setting. 3 Of all the LOs, 1 suppressed human peripheral blood lymphocyte proliferation aer concanavalin A treatment with an IC 50 of 2.5 mg mL À1 .…”
