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, RluA family; This group is comprised of eukaryotic, bacterial and archeal proteins similar to eight site specific Escherichia coli pseudouridine synthases: RsuA, RluA, RluB, RluC, RluD, RluE, RluF and TruA. Pseudouridine synthases catalyze the isomerization of specific uridines in a n RNA molecule to pseudouridines (5-ribosyluracil, psi) requiring no cofactors. E. coli RluC for example makes psi955, 2504 and 2580 in 23S RNA. Some psi sites such as psi1917 in 23S RNA made by RluD are universally conserved. Other psi sites occur in a more restricted fashion, for example psi2819 in 21S mitochondrial ribosomal RNA made by S. cerevisiae Pus5p is only found in mitochondrial large subunit rRNAs from some other species and in gram negative bacteria. The E. coli counterpart of this psi residue is psi2580 in 23S rRNA. psi2604in 23S RNA made by RluF has only been detected in E.coli.

Pseudouridine synthases similar to Saccharomyces cerevisiae RIB2; Pseudouridine synthase, Saccharomyces cerevisiae RIB2_like. This group is comprised of eukaryotic and bacterial proteins similar to Saccharomyces cerevisiae RIB2, S. cerevisiae Pus6p and human hRPUDSD2. S. cerevisiae RIB2 displays two distinct catalytic activities. The N-terminal domain of RIB2 is RNA:psi-synthase which makes psi32 on cytoplasmic tRNAs. Psi32 is highly phylogenetically conserved. The C-terminal domain of RIB2 has a DRAP deaminase activity which catalyses the formation of 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione 5'-phosphate from 2,5-diamino-6-ribitylamino-4(3H)-pyrimidinone 5'-phosphate during riboflavin biosynthesis. S. cerevisiae Pus6p makes the psi31 of cytoplasmic and mitochondrial tRNAs.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
