| heal.abstract | Human placental ATP diphosphohydrolase (ATP-DPH), has been previously characterized as an azide-sensitive, Ca(2+)- or Mg(2+)-dependent triphospho- and diphosphonucleosidase which migrates as an 82 kDa protein band on SDS-PAGE (Christoforidis, S. et al. (1995) Eur. J. Biochem. 234, 66-74). In this paper we have studied the subcellular localization of placental ATP-DPH by differential centrifugation and flotation experiments. Using specific enzymatic markers it was found that ATP-DPH is localized on plasma membrane. ATP-DPH was found to be a highly N-glycosylated protein which is a common post-translational modification of plasma membrane proteins. Extensive incubation of the native pure enzyme with N-glycosidase F resulted in the elimination of the 82 kDa form and the concurrent formation of a deglycosylated product of 57.5 kDa and four other intermediate products, indicating the presence of at least five N-glycosylation sites within the ATP-DPH molecule. The partially deglycosylated sample retained its activity in solution and in native gel electrophoresis and activity staining. | en |
