CC -!- FUNCTION: Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA
CC wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). Acts
CC by mediating the C-terminal thiocarboxylation of sulfur carrier URM1.
CC Its N-terminus first activates URM1 as acyl-adenylate (-COAMP), then
CC the persulfide sulfur on the catalytic cysteine is transferred to URM1
CC to form thiocarboxylation (-COSH) of its C-terminus. The reaction
CC probably involves hydrogen sulfide that is generated from the
CC persulfide intermediate and that acts as nucleophile towards URM1.
CC Subsequently, a transient disulfide bond is formed. Does not use
CC thiosulfate as sulfur donor; NFS1 probably acting as a sulfur donor for
CC thiocarboxylation reactions. Prior mcm(5) tRNA modification by the
CC elongator complex is required for 2-thiolation. May also be involved in
CC protein urmylation. {ECO:0000255|HAMAP-Rule:MF_03049}.
