Modification of L-asparaginase from Erwinia carotovora using human serum albumin.
L-Asparaginase from Erwinia carotovora was modified by coupling with human serum albumin. The complex retained 80% of the activity, shifted the pH optima to 7.0, and lowered the Km value by tenfold, but the temperature optima remained at 37 degrees C. It was also found to be heat-resistant.
