ABSTRACT
The presence of arginase in rat fibrosarcoma not synthesizing urea, suggested that this enzyme may have additional functions. Ornithine carbamoyl transferase, a key enzyme of the urea cycle was absent in this tissue, when compared to normal tissues, lower amount of ornithine was found in the fibrosarcoma, but this tumour contained a higher level of proline. The radioactivity present in L-[U-14C] arginine was incorporated into putrescine, spermidine, spermine, proline glutamate and glutamine suggesting that arginine was a possible precursor and that arginase may have a role in the synthesis of these metabolites.
