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). Also
CC essential during biosynthesis of the molybdenum cofactor. Acts by
CC mediating the C-terminal thiocarboxylation of sulfur carriers URM1 and
CC MOCS2A. Its N-terminus first activates URM1 and MOCS2A as acyl-
CC adenylates (-COAMP), then the persulfide sulfur on the catalytic
CC cysteine is transferred to URM1 and MOCS2A to form thiocarboxylation (-
CC COSH) of their C-terminus. The reaction probably involves hydrogen
CC sulfide that is generated from the persulfide intermediate and that
CC acts as nucleophile towards URM1 and MOCS2A. Subsequently, a transient
CC disulfide bond is formed. Does not use thiosulfate as sulfur donor;
CC NFS1 probably acting as a sulfur donor for thiocarboxylation reactions.
CC {ECO:0000255|HAMAP-Rule:MF_03049}.
