| 1 | Quantitative analyses were carried out on Tb3+ binding to porcine intestinal calcium-binding protein (CaBP). | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 2 | Tb3+ (emission at 547 nm) and intrinsic tyrosine (emission at 303 nm) fluorescences upon excitation at 260 nm increase almost in parallel with increasing Tb3+ concentration up to a molar ratio of 2 against the protein in the CaBP solution. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 3 | Tb3+ (emission at 547 nm) and intrinsic tyrosine (emission at 303 nm) fluorescences upon excitation at 260 nm increase almost in parallel with increasing Tb3+ concentration up to a molar ratio of 2 against the protein in the CaBP solution. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 4 | The pH dependence profile of Tb3+ fluorescence of the Tb3+-CaBP complex suggests that some free carboxylate groups are involved in the binding, as also suggested for Ca2+ binding. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 5 | The results of fluorometric titration of Tb3+ and intrinsic tyrosine fluorescences of the CaBP complex with Tb3+ or Ca2+ led us to conclude that Tb3+ and Ca2+ have two common binding sites for each CaBP molecule. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 6 | The results of fluorometric titration of Tb3+ and intrinsic tyrosine fluorescences of the CaBP complex with Tb3+ or Ca2+ led us to conclude that Tb3+ and Ca2+ have two common binding sites for each CaBP molecule. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 7 | The results of fluorometric titration of Tb3+ and intrinsic tyrosine fluorescences of the CaBP complex with Tb3+ or Ca2+ led us to conclude that Tb3+ and Ca2+ have two common binding sites for each CaBP molecule. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 8 | The results of fluorometric titration of Tb3+ and intrinsic tyrosine fluorescences of the CaBP complex with Tb3+ or Ca2+ led us to conclude that Tb3+ and Ca2+ have two common binding sites for each CaBP molecule. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 9 | Tb3+ strongly inhibits 45Ca binding to one of the two Ca2+-binding sites in the CaBP. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 10 | All of these and previous results indicate that each Tb3+ ion can bind to either of two high-affinity Ca2+-binding sites in porcine intestinal CaBP with an affinity different from that for Ca2+ ion. | tb3+ | S100 calcium binding protein G | Homo sapiens |
| 11 | We discuss the localization of the Ca2+- and Tb3+-binding sites in the CaBP. | tb3+ | S100 calcium binding protein G | Homo sapiens |
