CC -!- FUNCTION: Could be responsible for synthesis of pseudouridine from
CC uracil-55 in the psi GC loop of transfer RNAs. {ECO:0000255|HAMAP-
CC Rule:MF_01081}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=uridine(55) in tRNA = pseudouridine(55) in tRNA;
CC Xref=Rhea:RHEA:42532, Rhea:RHEA-COMP:10101, Rhea:RHEA-COMP:10102,
CC ChEBI:CHEBI:65314, ChEBI:CHEBI:65315; EC=5.4.99.25;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01081};
CC -!- SIMILARITY: Belongs to the pseudouridine synthase TruB family. Type 2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01081}.
