2. RNA turnover in yeast mitochondria So far the best characterized mitochondrial RNA decay system has been described for the yeast S. cerevisiae, because both genetical and biochemical analysis was available. Yeast RNA turnover is accomplished by the two-subunit protein complex called mtEXO or mitochondrial degradosome. It consists of an RNA helicase encoded by the nuclear gene SUV3 [10] and of an exoribonuclease encoded by the nuclear gene DSS1 [11]. Both proteins form a complex where t...
