Inactivated enzymes
WebApr 11, 2024 · The thermal effect of MW irradiation was the main cause of enzyme inactivation. The E a values required to inactivate the same enzymes were similar for both methods and the results for z values were consistent. Therefore, MWH and CTH have the same enzyme inactivation effect, but in different ways (Xu et al., 2016). WebThese enzymes, which include some of our key metabolic regulators, are often given the name of allosteric enzymes 2 ^2 2 squared. Allosteric enzymes typically have multiple active sites located on different protein subunits. When an allosteric inhibitor binds to an enzyme, all active sites on the protein subunits are changed slightly so that ...
