Complex I of winter wheat mitochondria respiratory chain is the most sensitive to uncoupling action of plant stress-related uncoupling protein CSP 310.
The influence of stress uncoupling protein CSP 310 on functional stability of different mitochondrial respiratory chain complexes was analysed using various substrates of the tricarboxylic acid cycle. Complex I was the most sensitive to CSP 310 uncoupling action whilst other complexes were more stabile. It is proposed that the key point of CSP 310 uncoupling action is complex I of plant mitochondrial respiratory chain.
