8639547-0	1996	Introduction of a fifth carboxylate ligand heightens the affinity of the oncomodulin CD and EF sites for Ca2+.	carboxylate	24-35	oncomodulin	Homo sapiens	73-84	
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+.	carboxylate	72-83	oncomodulin	Homo sapiens	19-30
