Lanthanoid Series Elements 8-19 carbonic anhydrase 2 Bos taurus 200-206 931985-2 1976 The substitution of lanthanide ions for Ca(II) in the Ca(II)-binding sites of prothrombin and the derivatives of prothrombin activation and in the metal-dependent conversion of prothrombin or prethrombin 1 to thrombin was studied at pH 6.8. Lanthanoid Series Elements 20-30 carbonic anhydrase 2 Bos taurus 40-46 931985-2 1976 The substitution of lanthanide ions for Ca(II) in the Ca(II)-binding sites of prothrombin and the derivatives of prothrombin activation and in the metal-dependent conversion of prothrombin or prethrombin 1 to thrombin was studied at pH 6.8. Lanthanoid Series Elements 20-30 carbonic anhydrase 2 Bos taurus 54-60 1167543-1 1975 The substitution of trivalent lanthanide ions for Ca(II) in the Ca(II)-DEPENDENT ACTIVATION OF BOVINE Factor X by the coagulant protein of Russell"s viper venom was studied at pH 6.8. Lanthanoid Series Elements 30-40 carbonic anhydrase 2 Bos taurus 64-70 1167543-9 1975 These data suggest that lanthanide ions complete with Ca(II) for the metal binding sites of Factor X and facilitate the formation of a nonproductive ternary complex of venom protein-Factor X-metal.
