Ki kinact determination

WebFor a competitive irreversible inhibitor, Ki,app = Ki (1+ [S]/Km), so you need to also measure the substrate's Km. There is another way to get kinact/Ki, which is to use numerical integration to perform a global fit of the whole set of progress curves at once. WebThe k inact and K I values determined can be used to predict the risk of drug-drug interactions. The FDA guidance for drug interactions (Jan 2024) 3 recommend determining k inact and K I if any time dependent loss of initial product formation rate is observed in …
