-
rapid reaction studies show that dithiothreitol generates a transient mixed disulfide intermediate with sfALR signaled by a weak charge-transfer interaction between the thiolate of C145 and the oxidized flavin, reducing the transfer of reducing equivalents and reoxidation of the reduced flavin by molecular oxygen

silences QSOX. Survival of QSOX-silenced insects is reduced over controls following blood digestion, most likely due to the compromised ability of mosquitoes to scavenge and/or prevent damage caused by blood meal-derived oxidative stress. Higher lipid peroxidation and mortality in QSOX-silenced mosquitoes may be an indication that the redox balance is altered in these insects after a blood meal
