Kovacs faculty website, via University of Washington Department of Chemistry website, July 1, 2020(Transition-metal-containing enzymes (metalloenzymes) promote a number of critical biological processes ranging from the biosynthesis of neurotransmitters, and hormones, to DNA replication and repair, the conversion of electrochemical to chemical energy, and the photosynthetic production of dioxygen (O₂))

Metalloenzymes, in Encyclopedia of geobiology, 2011, via SpringerLink, viewed July 1, 2020(Metalloenzymes are enzyme proteins containing metal ions (metal cofactors), which are directly bound to the protein or to enzyme-bound nonprotein components (prosthetic groups). About one-third of all enzymes known so far are metalloenzymes (see Holm et al., 1996 for a general overview). Besides enzymes, other metalloproteins are involved in non-enzyme electron transfer reactions (cytochromes), may act as storage (e.g., ferritin for iron) or transport proteins (e.g., transferrin for iron))
