Inhibitors WebbWhat is the recommended pH for Proteinase K to keep its enzyme activity? Proteinase K is a proteolytic enzyme that is purified from the Tritirachium album. Proteinase K is stable over a wide pH range 4.0–12.5 with an optimum of pH 8.0. What is the main applications of Proteinase K? See More >> How to dissolve proteinase K powder?
WebbThe pH activity curve of proteinase K, determined for the hydrolysis of urea-denatured hemoglobin, showed optimal activity in the pH range 7.5–12.0 ( 1 ). However, the enzyme is normally used in pH range 7.5–9.0 ( 1, 26, 27 ). 2.5 Assay The assay is based on the hydrolysis of N -acetyl- L -tyrosine ethylester (ATEE). WebbThe pH-optimum is at 8, but the enzyme is active over a wide pH-range (pH5 - 12). An elevation of the reaction temperature from 37°C to 50 - 60°C may increase the activity several times, like the addition of 0.5 - 1% SDS.
