The GSH indirectly support the detoxification of free radical components by its function as cosubstrate
of the antioxidant enzymes such as glutathione peroxidases (GPxs) (Regoli & Principato 1995).
Methylenetetrahydrofolate reductase (MTHFR) is the enzyme that catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a cosubstrate
for homocysteine remethylation to methionine (7,8).
These transfer electrons directly to the electrode thereby eliminating the need for the reduction of an oxygen cosubstrate
putida could not metabolize 1,5-dimethylnaphthalene even when naphthalene was used as a cosubstrate
Inhibition by N-oxalylamino acid derivatives, first developed for use with collagen prolyl 4-hydroxylases, further implies that these hydroxylases are also dependent upon 2OG as a cosubstrate
