MADD may be caused by mutations in the electron transfer flavoprotein
alpha subunit (ETFA),  electron transfer flavoprotein
beta subunit (ETFB), or electron transfer flavoprotein
dehydrogenase (ETFDH) genes.
1) reviews the current understanding of flavoproteins
, which play a role in catalyzing oxidation-reduction reactions and in other biological activities, and have now been identified and characterized from almost every organism known.
In many enzymes such as catalases and peroxidases as well as flavoproteins
iron is a key structural component [32,10].
Chromate-reducing properties of soluble flavoproteins
from Pseudomonas putida and Escherichia coli.
Meanwhile, the blue-light receptor cryptochromes, which are flavoproteins
in numerous plants and animals, are proposed to be the +magnetoreceptors.
Vitamin B2 (riboflavin, flavin adenine dinucleotide [FAD] [active form]) is a coenzyme in respiratory systems and a component of flavoproteins
with specific importance in Krebs cycle.
Monoamine oxidases (MAOs) are flavoproteins
which catalyze the oxidative deamination of a variety of neurotransmitters, such as noradrenaline, dopamine, and serotonin, as well as different exogenous and endogenous amines (i.
