Pseudouridine synthases catalyze the isomerization of specific uridines in an RNA molecule to pseudouridines (5-ribosyluracil, psi); Pseudouridine synthases contains the RsuA/RluD, TruA, TruB and TruD families. This group consists of eukaryotic, bacterial and archeal pseudouridine synthases. Some psi sites such as psi55,13,38 and 39 in tRNA are highly conserved, being in the same position in eubacteria, archeabacteria and eukaryotes. Other psi sites occur in a more restricted fashion, for example psi2604in 23S RNA made by E.coli RluF has only been detected in E.coli. Human dyskerin with the help of guide RNAs makes the hundreds of psueudouridnes present in rRNA and small nuclear RNAs (snRNAs). Mutations in human dyskerin cause X-linked dyskeratosis congenitas. Missense mutation in human PUS1 causes mitochondrial myopathy and sideroblastic anemia (MLASA).

Pseudouridine synthase, Escherichia coli TruB like; This group consists of bacterial pseudouridine synthases similar to E. coli TruB and Mycobacterium tuberculosis TruB. Pseudouridine synthases catalyze the isomerization of specific uridines in an RNA molecule to pseudouridines (5-ribosyluracil, psi). E. coli TruB and M. tuberculosis TruB make psi55 in the T loop of tRNAs. Psi55 is nearly universally conserved. E. coli TruB is not inhibited by RNA containing 5-fluorouridine.

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.

Pseudouridine synthase, TruB family; This group consists of eukaryotic, bacterial and archeal pseudouridine synthases similar to Escherichia coli TruB, Saccharomyces cerevisiae Pus4, M. tuberculosis TruB, S. cerevisiae Cbf5 and human dyskerin.

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.
