Mechanism of Ni(Fe)ARD action in methionine salvage pathway, in biosynthesis of ethylene, and role of Tyr-fragment as regulatory factor

368Role of Ni(Fe)-macrostructures due to H-bonds in mechanisms of Ni(Fe) ARD action in methionine salvage pathway, in biosynthesis of ethylene, is discussed. The AFM method was used for research of possibility of the stable supramolecular nanostructures formation based on Ni(Fe)ARD model system {Ni^II(acac) ₂ + MP + Tyr} (Tyr = L-Tyrosine)—with the assistance of intermolecular H-bonds. Using UV-spectroscopy, we received the confirmation of the of triple complexes {Ni(acac)₂-MP-Tyr} formation.
