TrxR belongs to the pyridine nucleotide-disulfide oxidoreductase family and is a dimeric flavoenzyme
(Lu et al.
MAOB is also an important flavoenzyme
in regulating the metabolic degradation of serotonin in nerve tissue or the target tissues .
As a member of the disulfide reductase family, TGR is a NADPH-dependent homodimeric flavoenzyme
with a dithiol/disulfide redox center located at the si face of the FAD prosthetic group .
Mannervik, "Purification and characterization of the flavoenzyme
glutathione reductase from rat liver," The Journal of Biological Chemistry, vol.
Structure of the flavoenzyme
vanillyl-alcohol oxidase in complex with phenol was shown (PDB: 1AHZ).
GR is the key enzyme of the ascorbat-glutation cycle for the removal of [H.sub.2][O.sub.2] in different cellular compartments  and a member of flavoenzyme
family which catalyzes the regenerates GSH from GSSG, with NADPH as a source of reducing power.
In the bacterium Clostridium kluyveri an NAD(P)H-dependent flavoenzyme
dihydrolipoyl dehydrogenase (synonymously called dihydrolipoamide dehydrogenase) reduces Fe(III) complexes of citrate, ATP, and ADP .
The structure of the flavoenzyme
niger; a flavoenzyme
synthesized inter and intracellular, is of prime importance in food and beverage industries (El-Sherbeny et al., 2005).
2-haloacrylate hydratase, a new class of flavoenzyme
that catalyzes the addition of water to the substrate for dehalogenation.
The identified enzymes involved in acetaldehyde production included alcohol dehydrogenase (ADH) and xanthine oxidoreductase (XO) in the cytosolic fraction and the flavoenzyme
NADPH oxidase and catalase in the microsomal fraction .
When antidepressants (which also include a group of betacarbolines) are used in the treatment of depression and Parkinson's disease, a suppression of the enzyme activity of monoaminooxidase--a flavoenzyme
which catalyzes the oxidative desamination of certain important biogenic amines--is observed .
