However, among two related yeast proteins, the archaeal set matches yeast YLR175w far better than YNL292w. The first, termed centromere/microtubule binding protein 5 (CBF5), is an apparent rRNA pseudouridine synthase, while the second is the exclusive tRNA pseudouridine 55 synthase for both cytosolic and mitochondrial compartments. It is unclear whether archaeal proteins found by this model modify tRNA, rRNA, or both. [Protein synthesis, tRNA and rRNA base modification]

Pseudouridine synthase, human dyskerin like; This group consists of eukaryotic and archeal pseudouridine synthases similar to human dyskerin, Saccharomyces cerevisiae Cbf5, and Drosophila melanogaster Mfl (minifly protein). Pseudouridine synthases catalyze the isomerization of specific uridines in an RNA molecule to pseudouridines (5-ribosyluracil, psi). No cofactor is required. S. cerevisiae Cbf5 and human dyskerin are nucleolar proteins that, with the help of guide RNAs, make the hundreds of psueudouridnes present in rRNA and small nuclear RNAs (snRNAs). Cbf5/Dyskerin is the catalytic subunit of eukaryotic box H/ACA small nucleolar ribonucleoprotein (snoRNP) particles. D. melanogaster mfl hosts in its fourth intron, a box H/AC snoRNA gene. In addition dyskerin is likely to have a structural role in the telomerase complex. Mutations in human dyskerin cause X-linked dyskeratosis congenitas. Mutations in Drosophila Mfl results in miniflies that suffer abnormalities.

PUA RNA-binding domain of the archaeal pseudouridine synthase component Cbf5; The RNA-binding PUA (PseudoUridine synthase and Archaeosine transglycosylase) domain was detected in a number of proteins involved in RNA metabolism. Members of the archaeal and eukaryotic subfamily of pseudouridine synthases, including Cbf5 (dyskerin in humans) and similar proteins, are modules that assist in the binding and positioning (guide and/or substrate) of RNA to the pseudouridine synthase complex. Pseudouridine synthases are enzymes that are responsible for post-translational modifications of RNAs by specifically isomerizing uracil residues. In Pyrococcus furiosus H/ACA ribonucleoprotein (RNP) assembly with a single-hairpin H/ACA RNA, the lower stem and the ACA motif of the guide RNA are anchored at the PUA domain of Cbf5. In addition, the N-terminal extension of Cbf5, which is a hot spot for dyskeratosis congenita (a rare genetic form of bone marrow failure) mutation, forms an extra structural layer on the PUA domain.

tRNA pseudouridine(55) synthase; TruB, the tRNA pseudouridine 55 synthase, converts uracil to pseudouridine in the T loop of most tRNAs in all three domains of life. This model is built on a seed alignment of bacterial proteins only. Saccharomyces cerevisiae protein YNL292w (Pus4) has been shown to be the pseudouridine 55 synthase of both cytosolic and mitochondrial compartments, active at no other position on tRNA and the only enzyme active at that position in the species. A distinct yeast protein YLR175w, (centromere/microtubule-binding protein CBF5) is an rRNA pseudouridine synthase, and the archaeal set is much more similar to CBF5 than to Pus4. It is unclear whether the archaeal proteins found by this model are tRNA pseudouridine 55 synthases like TruB, rRNA pseudouridine synthases like CBF5, or (as suggested by the absence of paralogs in the Archaea) both. CBF5 likely has additional, eukaryotic-specific functions. The trusted cutoff is set above the scores for the archaeal homologs of unknown function, so yeast Pus4p scores between trusted and noise.

Additionally, the PUA domain was detected in a family of eukaryotic proteins that also contain a domain homologous to the translation initiation factor eIF1/SUI1; these proteins may comprise a novel type of translation factors. Unexpectedly, the PUA domain was detected also in bacterial and yeast glutamate kinases; this is compatible with the demonstrated role of these enzymes in the regulation of the expression of other genes. It is predicted that the PUA domain is an RNA binding domain.

It is also found in rRNA pseudouridine synthase, another enzyme of RNA base modification not otherwise homologous to tgt. It is found, again at the C-terminus, in two putative glutamate 5-kinases.
