Calculate the Turnover Number (kcat) for enzyme kinetics analysis. Enter Vmax and total enzyme concentration to calculate kcat. The Turnover Number (kcat) is a key parameter in enzyme kinetics that represents the maximum number of substrate molecules converted to product per enzyme molecule per second.

Feb 3, 2024 · The Kcat Calculator is a valuable tool used in enzymology to determine the catalytic efficiency of an enzyme. It calculates the catalytic constant, represented by kcat, which measures the rate at which an enzyme converts its substrate …

K cat is a parameter that measures the catalytic efficiency of an enzyme. The K cat value represents the number of substrate molecules an enzyme can convert into a product per unit of time when fully saturated with substrates. K cat is also referred to as the turnover number or catalytic constant.

To calculate kcat, you first need to determine the concentration of active enzyme present in your experiment ([E]). This value can be determined through multiple methods, such as measuring protein absorbance at 280 nm or using a Bradford assay.

If you know the concentration of enzyme sites you've added to the assay (E t) then you can calculate the catalytic constant K cat. It is defined to equal V max /E t. Vmax and the Y values (enzyme velocities) are expressed in units of concentration per time, and Et must be entered in those same concentration units.

Dec 27, 2020 · The kcat equation, also known as the Michaelis-Menten equation, lets you figure out how fast a reaction occurs with a catalyst. Make sure to use appropriate kcat units so you can apply them correctly.

Jun 5, 2020 · This Michaelis-Menten equation calculator determines parameters of enzyme-controlled reactions, from rates of reaction to substrate concentration and Michaelis constant.

Kcat is the turnover number that describes the number of times each enzyme site converts substrate to product per unit time. A Kcat of 5/second means that that enzyme makes five molecules of product per molecule of enzyme per second. Formula to calculate Kcat.

As a beginner, you may find it easier to use Eisenthal & Cornish-Bowden's "direct linear plot" of your data to determine Vmax and Km than a regression of v against [S]. As a non-parametric method,...
