| Abstract: | Sequence profile searches were used to identify an ancient domain in ThiI-like thiouridine synthases, conserved RNA methylases, archaeal pseudouridine synthases and several uncharacterized proteins. We predict that this domain is an RNA-binding domain that adopts an alpha/beta fold similar to that found in the C-terminal domain of translation initiation factor 3 and ribosomal protein S8. |
