COMMENTARY
LITERATURE
physiological function
-
PfNDH2 is a principal electron donor to the electron transport chain, linking fermentative metabolism to the generation of mitochondrial electrochemical membrane potential, an essential function for parasite viability. PfNDH2 is involved in the redox reaction of NADH oxidation with subsequent quinol production

-
-
-
additional information
?
-
-
enzyme is most active toward naphtho- and benzoquinones, whereas ferricyanide and dichlorophenolindophenol are less efficient. Enzyme reacts with ubiquinone Q-l, but ubiquinones with a long side-chain such as Q-5 and Q-10 are virtually inactive as electron acceptors
