Like the Ni-CODHs, the [NAD.sup.+]-independent FDHs are also extremely sensitive to atmospheric dioxygen, and their manipulation also requires strictly anaerobic conditions.
Mono-functional heme-catalase (catalase) dismutates hydrogen peroxide ([H.sub.2][O.sub.2]) into water and dioxygen. [H.sub.2][O.sub.2] is both toxic to cells and used as a second messenger for cellular regulation [43].

For TEM observation, rat pancreatic tissue specimens were fixed in 2% glutaraldehyde for 24 h, stained with acetic acid dioxygen oil and lead citrate, and finally observed under a TEM (JEM-1230, JEOL Ltd., Japan) by an expert who was blind to this experiment.

It is important to note that despite directly interacting with dioxygen, COX itself is not known to generate ROS--this function is specifically linked to the NADH dehydrogenase and [bc.sub.1] complexes of the ETC [27-29].
A central molecule in ROS is the superoxide anion, which is generated when a single electron is transferred to dioxygen. Superoxide does not cross membranes readily; however, it is rapidly converted to [H.sub.2][O.sub.2], either spontaneously or catalyzed by cellular enzymes such as superoxide dismutase.
