DETERMINATION OF THE OPTIMUM CONDITIONS FOR UREASE EXTRACTED FROM SOME LOCAL PLANTS

In the current study, Seventeen types of plants commonly used namely (Chickpeas, Tomato, Soybean, Mustard, Baker, Lebbeck, Bean, Sesame, Male Iraqi berries, Female Indian Potato, Radish, Legumes, peas, Watermelon, and Phaseolus were obtained screened for urease activity, among these plants, Sesame was chosen with maximum enzymatic it had highest productivity enzyme (1.623 U/mg protein). The optimum extraction ratio represented by 1:10 (W: V) after 90 minutes 0.8414U/mg protein. Sodium phosphate buffer (0.1 M, pH 7.0) as best specific activity 0.9004U/mg
