glutamine synthetase and arginase are mitochondrial enzymes in uricotelic species , but are normally found in the cytoplasm in ureotelic species . the properties of the elasmobranch arginase , however , are characteristic of arginases from ureotelic species ( e.g . the km for arginine is 1.2 mm , and the enzyme has an mr congruent to 100,000 ) .
