New method quantifies accuracy intervals for K m in enzyme kinetics, indicating improved reliability of estimates.

To improve the accuracy assessment of the Michaelis constant in enzyme kinetics by addressing gaps in current methodologies.
Introduced the ACI‐K m framework to assess accuracy through a binding‐isotherm formulation.
Quantified the impact of systematic uncertainties in enzyme and substrate concentrations on K m values.
Developed a web application to implement the ACI‐K m approach.
Showed that traditional K m ± SE underestimates uncertainty.
Demonstrated that ACI provides more reliable accuracy bounds, aiding decision-making.

Wang et al. (2025) studied this question.
