0 an ion (= an atom or small group of atoms that has an electrical charge) or a molecule (= the simplest unit of a chemical substance) that is attached to a metal atom
The development of both types of ligands could therefore have important biomedical implications.
Studies such as presented here can serve to provide the data necessary for application of opioid ligands in such unique settings.
The sharing of these receptors by multiple cytokines raises the question of how the ligands can trigger specific responses in the target cells.
Thus, the net effect of the mixture of the two ligands at the level of the whole animal will be the combined effect.
The latter may either cooperate in binding heme or might bind distinct ligands.
Our data in conjunction with those of other laboratories indicates the differences in orientation of different ligands within the same binding cleft.
Polycystin-1 comprises multiple extra- and intracellular protein domains that suggest many different protein ligands and hence many different cellular functions.
However, under nutrient limiting conditions in the environment, microorganisms may secrete ligands, such as siderophores, to scavenge trace metal micronutrients.
