Metals 14-19 oncomodulin Homo sapiens 74-85 3571255-6 1987 Analyses of the distribution of metal-bound oncomodulin species showed that Ca(II)----Lu(III) exchange was cooperative, the coefficient of cooperativity being estimated as 5 +/- 1. Metals 32-37 oncomodulin Homo sapiens 44-55 3571255-7 1987 The kinetics of the release of Yb(III) from oncomodulin as measured by optical stopped-flow techniques corroborated the observed cooperativity in metal binding; the off-rate constant of Yb(III) from the EF site of Yb2-oncomodulin was 0.0036 s-1, approximately 19 times slower than the release of Yb(III) from the EF site of Ca1Yb1-oncomodulin. Metals 146-151 oncomodulin Homo sapiens 44-55 3571255-16 1987 Hence, we suggest that Asp-59 in oncomodulin binds metal only indirectly through an intervening water molecule, a proposal which is consistent with the CD site"s reduced affinity for ions the size of Ca(II) or smaller. Metals 51-56 oncomodulin Homo sapiens 33-44 8489002-1 1993 In this study, the CD loop of the Ca(2+)-binding protein oncomodulin was replaced by a high-affinity, metal-binding sequence that was found to reverse the order of fill of the two sites in the protein. Metals 102-107 oncomodulin Homo sapiens 57-68 1618836-11 1992 The mutant loop inserted into oncomodulin had 32 times more Tb3+ luminescence than the identical synthetic peptide, despite having the same donor tryptophan and metal binding ligands. Metals 161-166 oncomodulin Homo sapiens 30-41 24233453-0 1994 Effects of metal ion binding on an oncomodulin mutant containing a novel calcium-binding loop. Metals 11-16 oncomodulin Homo sapiens 35-46 1854760-0 1991 Metal-induced changes in the fluorescence properties of tyrosine and tryptophan site-specific mutants of oncomodulin. Metals 0-5 oncomodulin Homo sapiens 105-116
