Abstract

A comparative analysis of a dependence of protein synthesis in mitochondria of cultivated (Zea mays) and wild (Elymus sibiricus) cereals on redox conditions showed that the addition of oxidized glutathione enhanced and the addition of reduced glutathione suppressed translation in organello. Inhibitors of protein kinases and protein phosphatases modified substantially the effects of redox agents on protein synthesis in mitochondria. It is supposed that protein phosphorylation in mitochondria may be a mechanism mediating the interrelation between the redox state of the respiratory chain and the activity of mitochondrial translation.
