Michaelis–Menten curve A graph that shows the relationship between the concentration of a substrate and the rate of the corresponding enzyme-controlled reaction. Named after L. Michaelis (1875–1949) and M. L. Menten (1879–1960), the curve only applies to enzyme reactions involving a single substrate. The graph can be used to calculate the Michaelis constant (Km), which is the concentration of a substrate required in order for an enzyme to act at half of its maximum velocity (Vmax). The Michaelis constant is a measure of the affinity of an enzyme for a substrate. A low value corresponds to a high affinity, and vice versa. See also enzyme kinetics.
