E290C | formation of a covalent complex with cytochrome c mutant K79C, kinetic studies. Residual activity of complex is due to unreacted enzyme that copurifies with the complex. In the complex, the Pelletier-Kraut site is blocked which results in zero catalytic activity | Saccharomyces cerevisiae |
