Cadmium 52-54 oncomodulin Homo sapiens 40-51 9636056-0 1998 Interconversion of the ligand arrays in the CD and EF sites of oncomodulin. Cadmium 44-46 oncomodulin Homo sapiens 63-74 7827057-0 1995 Interconversion of the CD and EF sites in oncomodulin. Cadmium 23-25 oncomodulin Homo sapiens 42-53 8639547-5 1996 Interestingly, for oncomodulin, we observe that introduction of a fifth carboxylate residue at the +z position in the CD coordination sphere or at the -x position in the EF coordination sphere significantly increases the affinity of those sites for Ca2+. Cadmium 118-120 oncomodulin Homo sapiens 19-30 7628071-2 1995 DESIGN AND METHODS: A mutant of oncomodulin with a cysteine residue at position 57 located in the CD binding loop was conjugated to a salicylic acid group. Cadmium 98-100 oncomodulin Homo sapiens 32-43 7827057-7 1995 As in other parvalbumins, the liganding residues in the CD and EF sites of oncomodulin differ at the +z and -x coordination positions: serine and aspartate, respectively, in the CD site; aspartate and glycine in the EF site. Cadmium 56-58 oncomodulin Homo sapiens 75-86 7827057-7 1995 As in other parvalbumins, the liganding residues in the CD and EF sites of oncomodulin differ at the +z and -x coordination positions: serine and aspartate, respectively, in the CD site; aspartate and glycine in the EF site. Cadmium 178-180 oncomodulin Homo sapiens 75-86 7827057-20 1995 In wild-type oncomodulin, the CD site signal dominates the low-pH spectrum. Cadmium 30-32 oncomodulin Homo sapiens 13-24 3571255-5 1987 Lineshape analyses of several 1H NMR resonances generated by the Lu(III) titration of Ca2-oncomodulin indicated that Ca(II)----Ln(III) exchange at the CD site was 15-20 s-1, approximately 100 times faster than exchange at the CD site of parvalbumins. Cadmium 151-153 oncomodulin Homo sapiens 90-101 24233453-1 1994 The Ca(2+)-binding protein oncomodulin was altered by cassette mutagenesis of the CD site (CDOM33) with a sequence that was derived by a consensus method using over 250 known Ca(2+)-binding loop sequences. Cadmium 82-84 oncomodulin Homo sapiens 27-38 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. Cadmium 19-21 oncomodulin Homo sapiens 57-68 2108959-11 1990 The characteristics of Ca2+ binding to the specific site (likely the CD domain) are different from those of the Ca2+ specific sites in troponin C and in calmodulin and suggest that in oncomodulin hydrophobic forces do not play a predominant role in the binding process at the specific site. Cadmium 69-71 oncomodulin Homo sapiens 184-195 3571255-5 1987 Lineshape analyses of several 1H NMR resonances generated by the Lu(III) titration of Ca2-oncomodulin indicated that Ca(II)----Ln(III) exchange at the CD site was 15-20 s-1, approximately 100 times faster than exchange at the CD site of parvalbumins. Cadmium 226-228 oncomodulin Homo sapiens 90-101 3571255-8 1987 We attribute part of the reduced preference of small Ln(III)s for the CD site of oncomodulin to a combination of this site"s inherent incompressibility (Williams, T.C., Corson, D.C. & Sykes, B.D. Cadmium 70-72 oncomodulin Homo sapiens 81-92 3571255-14 1987 Like the CD site in oncomodulin, site III in troponin C has not only a lower affinity for calcium relative to the CD site of parvalbumins but also aspartic acid at its -X position; a water molecule bridges the gap between bound metal and the carboxyl group of the relatively short side chain of Asp-114 (Herzberg, O. Cadmium 9-11 oncomodulin Homo sapiens 20-31 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.
