KmP value and equilibrium constant
The Km value for the product is assumed to be similar but slightly higher than the the Km value of the substrate because of the similarity of the both species. Therefore the Km value of the substrate is multiplied by 1.05 to gain the one of the product and the uncertainty is increased by increasing the error on Kmsubstrate by 50%.
For information about the equilibrium constant please see here.
