✦ Synopsis

This review touches the most common instances where non-innocent ("suspect") behaviour of redoxactive ligands, either substrates or supporting components, is observed in a biochemical context. These ligands include the O 2 /O 2

•-/O 2 2-, NO + /NO • /NO -, o-quinone/o-semiquinone/catecholate and tyrosyl/tyrosinate redox systems, the tetrapyrrole (porphyrinic) ligands, the pterins and flavins, and the dithiolene/ene-dithiolate ligands in molybdo-and tungstopterin. These non-innocent ligands are discussed in their interaction with biological iron, copper, manganese, molybdenum or tungsten centers.
