Abstract: | The addition of cold shock CSP310 protein to mitochondria isolated from both monocotyledonous (rye, wheat, and maize) and dicotyledonous (pea) plants uncoupled oxidation from phosphorylation. This uncoupling was caused neither by the damage to mitochondrial membranes nor by the activation of alternative cyanide-resistant oxidase. As distinct from the classical plant uncoupling mitochondrial protein (PUMP), CSP310 uncoupling effect was insensitive to BSA. Therefore, we believe that the mechanism of CSP310 action differs from that of known plant uncoupling proteins. |
