CC   -!- FUNCTION: Could be responsible for synthesis of pseudouridine from
CC       uracil-13 in transfer RNAs. {ECO:0000255|HAMAP-Rule:MF_01082}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=uridine(13) in tRNA = pseudouridine(13) in tRNA;
CC         Xref=Rhea:RHEA:42540, Rhea:RHEA-COMP:10105, Rhea:RHEA-COMP:10106,
CC         ChEBI:CHEBI:65314, ChEBI:CHEBI:65315; EC=5.4.99.27;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01082};
CC   -!- SIMILARITY: Belongs to the pseudouridine synthase TruD family.
CC       {ECO:0000255|HAMAP-Rule:MF_01082}.
