Divalent ions as mediators of carbonylation in cardiac myosin binding protein C

November 1, 2023
Author(s)
Christina Bergonzo, Baikuntha Aryal, Ashutosh Rao
The dosing and efficacy of chemotherapeutic drugs can be limited by toxicity caused by off-pathway reactions. One hypothesis for how such toxicity arises is via metal-catalyzed oxidative damage of cardiac myosin binding protein C (cMyBP-C) found in cardiac
