CC   -!- FUNCTION: Involved in the post-transcriptional modification of the
CC       uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and
CC       tRNA(Gln). Catalyzes the conversion of 2-thiouridine (S2U-RNA) to 2-
CC       selenouridine (Se2U-RNA). Acts in a two-step process involving
CC       geranylation of 2-thiouridine (S2U) to S-geranyl-2-thiouridine (geS2U)
CC       and subsequent selenation of the latter derivative to 2-selenouridine
CC       (Se2U) in the tRNA chain. {ECO:0000255|HAMAP-Rule:MF_01622}.
