WebSep 5, 2024 · The proposed two-step mechanism for the SK-catalysed phosphoryl transfer reaction is presented in Figure 6 a–d. Reactants are kept in place by the two long arm residues K14 and R116 and the Mg 2+ ion. Upon reaching the two TSs, K14 and R116 show high flexibility which is reflected in the displacement of their terminal groups. WebWhat general factors contribute to the high phosphoryl-group transfer of ATP? Ans: Resonance stabilization, electrostatic repulsion, and stabilization due to hydration are important. Section: 15.
