Regular Paper pH Profile of cytochrome c-catalyzed tyrosine nitration*
In the present study, we investigated how cytochrome c catalyzed the nitration of tyrosine at various pHs. The cytochrome c-catalyzed nitration of tyrosine occurred in proportion to the concentration of hydrogen peroxide, nitrite or cytochrome c. The cytochrome c-catalyzed nitration of tyrosine was inhibited by catalase, sodium azide, cystein, and uric acid. These results show that the cytochro...

متن کاملMechanism of glyceraldehyde-3-phosphate dehydrogenase inactivation by tyrosine nitration.
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a multifaceted protein that is involved in numerous processes including glycolysis, translational silencing, transcriptional regulation of specific genes, and acting as a nitric oxide sensor. The precise mechanism on how GAPDH is targeted to these different roles is unclear but believed to involve specific posttranslational modification to the...
متن کاملDiabetes-associated nitration of tyrosine and inactivation of succinyl-CoA:3-oxoacid CoA-transferase.
High levels of reactive species of nitrogen and oxygen in diabetes may cause modifications of proteins. Recently, an increase in protein tyrosine nitration was found in several diabetic tissues. To understand whether protein tyrosine nitration is the cause or the result of the associated diabetic complications, it is essential to identify specific proteins vulnerable to nitration with in vivo m...
متن کاملMouse mammary gland involution is associated with cytochrome c release and caspase activation
At weaning, milk producing mammary epithelial cells undergo apoptosis and are removed by phagocytosis. Here, we show that mouse mammary gland involution is associated with mitochondrial cytochrome c release and processing of numerous caspases, including caspase-1, -3, -7, -8 and -9. Induction of caspase-3-like activity paralleled cleavage of poly-(ADP--ribose) polymerase. Dexamethasone inhibite...
