Chains	Accession	Name	Description	Comments	Source
B	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain

B	PF12513	ATP-dependent RNA helicase SUV3 C-terminal domain (SUV3_C)	ATP-dependent RNA helicase SUV3 C-terminal domain	This domain is found in bacteria and eukaryotes, and is approximately 50 amino acids in length. The domain is found in association with Pfam:PF00271 and it is found in ATP-dependent RNA helicase SUV3 from eukaryotes. The yeast mitochondrial degradoso ...	This domain is found in bacteria and eukaryotes, and is approximately 50 amino acids in length. The domain is found in association with Pfam:PF00271 and it is found in ATP-dependent RNA helicase SUV3 from eukaryotes. 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.	Domain
A	PF00773	RNB domain (RNB)	RNB domain	This domain is the catalytic domain of ribonuclease II [1].	Domain
