Abstract

Minerals are essential to different biological processes in living beings. Likewise, free transition metals such as copper and iron promote the formation of reactive oxygen species (ROSs). However, metal-binding peptides obtained by enzymatic hydrolysis of proteins or synthesized by solid-phase peptide synthesis avoid ROS formation catalyzed by free transition metals. Interactions between metals and mineral-binding peptides (MBPs) are usually studied using spectroscopic techniques, isothermal titration calorimetry, and more recently by surface plasmon resonance and switchSENSE. Through electrospray ionization-mass spectrometry, the changes in the binding affinities can be studied. MBPs can be purified using immobilized metal-ion affinity chromatography, and its process simulation. Various cellular models are used to investigate the health effects of MBPs.
