malfunction
the lack of a significant effect on deletion of the genes from Streptococcus mutans suggests the presence of additional antioxidant proteins in this bacterium
physiological function
-
although Pyrococcus furiosus is a strict anaerobe, it may tolerate oxygen to some extent. NOX1 may be involved in the response to oxygen at high temperatures
physiological function
-
further investigation is required to conclude firmly if the purified NADH oxidase is part of an enzyme system that protects anaerobic Thermotoga hypogea from accidental exposure to O2
physiological function
Nox-1 is a protective protein against oxygen toxicity
physiological function
the enzyme may be involved in electron transfer reactions resulting in sulfate respiration
physiological function
the fact that the expression of the Nox enzymes is not regulated suggests that they have some fundamental metabolic role, and not an occasional role during oxygen stress
