Biometals are trace elements that human beings require in very small amounts. This volume addresses transporters and transporter receptors of biometals in humans and provides current knowledge about the interaction between the toxic metal cadmium and essential metals zinc, copper, and magnesium. The 14 papers also discuss ferric uptake regulators, a superfamily of prokaryotic transcription factors that operate at the primary steps in the hierarchy of stress responses, and methods for detecting phytochelatins, a class of heavy metal binding peptides produced by higher plants, algae, and fungi.
