In this study, we attempted to uncover the reasons why Tautomycetin thioesterase (TMC TE) prefers hydrolysis rather than macrocyclization, and reveal the molecular basis of TE-catalyzed hydrolysis and macrocyclization.

Theoretical Results

The detailed mechanism of NO oxidation catalyzed by ZSM5 supported Mn/Co–Al/Ce is investigated and revealed by Quantum Chemistry Calculation. A three-step catalytic mechanism for NO oxidation is proposed and studied. Theoretical results show that, the activate energies of reactions catalyzed by ZSM-5 supported Mn/Co (71.1[Formula: see text]kJ/mol/80.6[Formula: see text]kJ/mol) are much lower than that obtained from the direct NO oxidation. This indicates that the ZSM-5 supported Mn/Co has an obvious catalytic effect. When the active center Si is replaced by Al and Ce, the activation energies are further decreased to about 40[Formula: see text]kJ/mol. This indicates that the doping of Al and Ce can obviously improve the catalytic effect. The theoretical study illustrates that the catalysts for NO oxidation not only relate to the supported transition metal such as Co and Mn, but also highly relate to the activity centers such as Al and Ce.
