Enzymes containing molybdenum or tungsten at their active sites appear to be present in all
forms of life, from ancient archaea to man. These enzymes catalyze a wide range of …

Since their introduction in 1967, poly (pyrazolyl)-borates1 have found wide application in
coordination chemistry, and their complexes with most metals or metalloids of the periodic …

Molybednum-containing enzymes (Coughlan, 1980; Spiro, 1985) occupy a significant place
in the development of the field now termed inorganic biochemistry. The importance of the …

Fly ash (FA) has been widely used to improve concrete sustainability for many years;
however, the amount of FA has been limited by the relatively low cement contents in …

Publisher Summary This chapter presents a discussion on the bioinorganic chemistry of
pterin-containing molybdenum and tungsten enzymes. The chapter focuses on the current …

The enzyme, hepatic sulfite oxidase, is responsible for the physiologically important
oxidation of sulfite to sulfate. 1 This enzyme is dimeric with each monomer containing a …

Formate dehydrogenase H, FDH (Se), from Escherichia coli contains a molybdopterin
