Comments [?]

case <OC:Escherichia>
Function Catalyzes oxygen-dependent 5-hydroxyuridine (ho5U) modification at position 34 in tRNAs, the first step in 5-carboxymethoxyuridine (cmo5U) biosynthesis. May be part of an alternate pathway, which is able to bypass cmo5U biogenesis in a subset of tRNAs under aerobic conditions.
else
Function Catalyzes oxygen-dependent 5-hydroxyuridine (ho5U) modification at position 34 in tRNAs.
end case
Catalytic activity RHEA:64224: AH2 + O2 + uridine(34) in tRNA = 5-hydroxyuridine(34) in tRNA + A + H2O
Similarity Belongs to the TrhO family.
