Catalytic Efficiency of Enzymes - Chemistry LibreTexts

In the field of biochemistry, the specificity constant (also called kinetic efficiency or ), is a measure of how efficiently an enzyme converts substrates into products. A comparison of specificity constants can also be used as a measure of the preference of an enzyme for different substrates (i.e., substrate specificity). The higher the specificity constant, the more the enzyme "prefers" that substrate. Webbd[P] dt = k2[ES]ss = k2[E]0[S] [S] + k − 1 + k2 k1 = k2[E]0[S] [S] + KM. where KM is the Michaelis constant.
