title: On urea formation in marine mammals.
abstract: Ornithine carbamoyltransferase (EC 2.1.3.3) has been determined in homogenates of liver of the sei whale (Balaenoptera borealis), the bottle-nose dolphin (porpoise) (Tursiops truncatus) and California sea lion (Zalophus californianus). These marine mammals show levels of this ornithine-urea cycle enzyme which are typical of terrestrial mammals.
