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 (By similarity). {ECO:0000250}.
