Theoretical insights into the reductive metabolism of CCl4 by cytochrome P450 enzymes and the CCl4-dependent suicidal inactivation of P450

31 August, 2014 - 08:17

Dalton Trans., 2014, Advance Article
DOI: 10.1039/C4DT02065K, PaperXiao-Xi Li, Qing-Chuan Zheng, Yong Wang, Hong-Xing Zhang
The one-electron reduction product, [radical dot]CCl3, irreversibly inactivates P450 via covalently binding to the meso-carbon, whereas the two successive one-electron reductions product, :CCl2, reversibly inhibits P450 by coordinating to iron.
