| Abstract/Contents: | The activity, stability, and kinetic characteristics of soil urease are examined and compared with those of a crude enzyme-organic matter extract from soil and of jack bean urease. Methods of organic matter extraction from soil are discussed and the resistance of all three forms of urease to irradiation, proteolysis, temperature, storage and lyophilization is assessed. In addition, measurements are made of Michaelis constants and pH optima. The data confirm previous observations in that at least a proportion of soil urease is remarkably stable in conditions which rapidly inactivate jack bean urease. Stability is maintained with the enzymically-active organic extract. |
