|
|
|
|
|
|
||
| UniProt code: O30033. |
|
||
| Organism: | |
Archaeoglobus fulgidus (strain ATCC 49558 / VC-16 / DSM 4304 / JCM 9628 / NBRC 100126). |
| Taxonomy: | |
Archaea; Euryarchaeota; Archaeoglobi; Archaeoglobales; Archaeoglobaceae; Archaeoglobus. |
|
||
|
||
| Function: | |
Non-catalytic component of the exosome, which is a complex involved in RNA degradation. Increases the RNA binding and the efficiency of RNA degradation. Helpful for the interaction of the exosome with A-poor RNAs (Probable). {ECO:0000305|PubMed:16285927, ECO:0000305|PubMed:20392821}. |
|
||
| Subunit: | |
Component of the archaeal exosome complex. Forms a trimer of Rrp4 and/or Csl4 subunits. The trimer associates with a hexameric ring- like arrangement composed of 3 Rrp41-Rrp42 heterodimers. Interacts with DnaG (Probable). {ECO:0000305|PubMed:16285927, ECO:0000305|PubMed:20392821}. |
| Subcellular location: | |
Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00975}. |
| Domain: | |
Contains an N-terminal domain that mediates interactions with the hexameric ring, a central S1 domain and a C-terminal zinc-ribbon domain. {ECO:0000269|PubMed:16285927}. |
| Miscellaneous: | |
The zinc ion has probably a structural role. {ECO:0000305|PubMed:16285927}. |
| Similarity: | |
Belongs to the CSL4 family. {ECO:0000255|HAMAP- Rule:MF_00975}. |
