1 The apparent Km and Vmax of ATP-dependent Sr2+ uptake were both higher than those for Ca2+ uptake. strontium cation carbonic anhydrase 2 Rattus norvegicus
2 ATP-dependent Sr2+ uptake by BLM vesicles diminished in the presence of 0.1 microM Ca2+ and was more markedly inhibited by 1 microM Ca2+. strontium cation carbonic anhydrase 2 Rattus norvegicus
3 ATP-dependent Sr2+ uptake by BLM vesicles diminished in the presence of 0.1 microM Ca2+ and was more markedly inhibited by 1 microM Ca2+. strontium cation carbonic anhydrase 2 Rattus norvegicus
4 Hill plots of Sr2+ uptake data with and without 0.1 microM Ca2+ showed that the cooperative behavior of Sr2+ uptake was not changed by Ca2+. strontium cation carbonic anhydrase 2 Rattus norvegicus
5 In the presence of 0.1 microM Ca2+, the affinity of the transport system for Sr2+ and the velocity of Sr2+ uptake in the BLM were both decreased. strontium cation carbonic anhydrase 2 Rattus norvegicus
6 In the presence of 0.1 microM Ca2+, the affinity of the transport system for Sr2+ and the velocity of Sr2+ uptake in the BLM were both decreased. strontium cation carbonic anhydrase 2 Rattus norvegicus
7 These results suggest that Ca2+ is preferentially transported in the renal cortex BLM when Ca2+ and Sr2+ are present at the same time. strontium cation carbonic anhydrase 2 Rattus norvegicus
