Mitochondrial degradasome RNA helicase subunit, C-terminal domain (IPR022192)

Short name: SUV3_C

Overlapping homologous superfamilies


Domain relationships



This domain is found in ATP-dependent RNA helicase SUV3. It is found in bacterial and eukaryotic proteins, it is approximately 50 amino acids in length and it is usually found in association with PF00271.

The yeast mitochondrial degradosome (mtEXO) is an NTP-dependent exoribonuclease involved in mitochondrial RNA metabolism. mtEXO is made up of two subunits: an RNase (DSS1) and an RNA helicase (SUV3). These co-purify with mitochondrial ribosomes [PMID: 12426313].
