The dynamic field of flavin and flavoprotein biochemistry has seen rapid advancement in recent years. Thisfirst book of thetwo volume set provides an overview of all aspects focussing on oxidases, dehydrogenases and related systems. Discussed arerecent developments in this field including those of large membrane-integral electron transfer complexes.It is an essential reference for all researchers in biochemistry, chemistry, photochemistry and photophysics working on flavoenzymes.
