An inhibitor of protein arginine methyltransferases, 7,7'-carbonylbis(azanediyl)bis(4-hydroxynaphthalene-2-sulfonic acid (AMI-1), is a potent scavenger of NADPH-oxidase-derived superoxide.

ABSTRACT: The methylation of proteins is an important post-translational mechanism that has been established to influence the activity of nuclear and nucleic acid binding proteins. Much less is known about the importance of protein methylation in the regulation of cytosolic proteins. Increased methylation of proteins is observed in cardiovascular disease and occurs in conjunction with elevated production of reactive oxygen species. However, the nature of the relationship between reactive oxygen species and protein methylation is poorly understood. Therefore, the goal of the current study was to determine whether protein methylation influences the catalytic activity of the NADPH oxidases (Nox), which are a family of enzymes responsible for the generation of superoxide. We found that the selective inh
