WebEnzyme unit. The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme 's catalytic activity. [1] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method. [2] WebDec 16, 2024 · So if you have protein concentration of X µg/µl and specific activity of Y pmole/µg min, then it equals to XY U/ml. For example, if the enzyme concentration is 0.147 µg/µl, and the specific activity is 152 pmol/ µg min, the enzyme concentration is: 0.147 µg/µl x 152 pmol/ µg min = 22 pmol/ µl min = 22 nmol/ min ml = 22 U/ml.
