CC -!- FUNCTION: Responsible for synthesis of pseudouridine from uracil-55 in
CC the psi GC loop of transfer RNAs. {ECO:0000256|HAMAP-Rule:MF_01080}.
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:0000256|ARBA:ARBA00000385, ECO:0000256|HAMAP-
CC Rule:MF_01080};
CC -!- SIMILARITY: Belongs to the pseudouridine synthase TruB family. Type 1
CC subfamily. {ECO:0000256|ARBA:ARBA00005642, ECO:0000256|HAMAP-
CC Rule:MF_01080}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
