CC   -!- FUNCTION: Catalyzes oxygen-dependent 5-hydroxyuridine (ho5U)
CC       modification at position 34 in tRNAs, the first step in 5-
CC       carboxymethoxyuridine (cmo5U) biosynthesis. May be part of an alternate
CC       pathway, which is able to bypass cmo5U biogenesis in a subset of tRNAs
CC       under aerobic conditions. {ECO:0000250|UniProtKB:P24188}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=AH2 + O2 + uridine(34) in tRNA = 5-hydroxyuridine(34) in tRNA
CC         + A + H2O; Xref=Rhea:RHEA:64224, Rhea:RHEA-COMP:11727, Rhea:RHEA-

CC         ChEBI:CHEBI:17499, ChEBI:CHEBI:65315, ChEBI:CHEBI:136877;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00469};
CC   -!- SIMILARITY: Belongs to the TrhO family. {ECO:0000255|HAMAP-
CC       Rule:MF_00469}.
