  • a Arginase specific activity was measured at 30°C after growth of the different strains on M.ammonia–25 μg of uracil per ml where indicated (∗). The specific activity is expressed in micromoles of urea produced per hour per milligram of protein. The values are the means of two independent assays, and the standard error was 10 to 15%.

  • b Corresponds to pRS416 CEN6 ARS4 URA3 SIN3.

  • c Corresponds to pRS416 CEN6 ARS4 URA3 RPD3.
