Mode opératoire

100 ml of a 1.25 molar, racemic solution of DL-arginine are mixed with 5·10-4 mol/l MnSO4.H2O, 2.5·10-4 mol/1 ascorbic acid and 14.0 mg L-arginase (=10000 U/(l·mol L-Arg)). After 22 hours, the conversion was 50% of the original amount of arginine and a corresponding amount of ornithine had been produced.
