CC -!- FUNCTION: Catalyzes the 2-thiolation of uridine at the wobble position
CC (U34) of tRNA, leading to the formation of s(2)U34. {ECO:0000255|HAMAP-
CC Rule:MF_00144}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + ATP + S-sulfanyl-L-cysteinyl-[protein] + uridine(34) in
CC tRNA = 2-thiouridine(34) in tRNA + A + AMP + diphosphate + H(+) + L-
CC cysteinyl-[protein]; Xref=Rhea:RHEA:47032, Rhea:RHEA-COMP:10131,
