CC   -!- FUNCTION: Acts as a sulfur carrier required for 2-thiolation of
CC       mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu)
CC       and tRNA(Gln). Serves as sulfur donor in tRNA 2-thiolation reaction by
CC       being thiocarboxylated (-COSH) at its C-terminus by the MOCS3 homolog
CC       UBA4. The sulfur is then transferred to tRNA to form 2-thiolation of
CC       mcm(5)S(2)U. Prior mcm(5) tRNA modification by the elongator complex is
CC       required for 2-thiolation. Also acts as a ubiquitin-like protein (UBL)
CC       that is covalently conjugated via an isopeptide bond to lysine residues
CC       of target proteins such as AHP1. The thiocarboxylated form serves as
CC       substrate for conjugation and oxidative stress specifically induces the
CC       formation of UBL-protein conjugates. {ECO:0000255|HAMAP-Rule:MF_03048}.
CC   -!- PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA
CC       biosynthesis. {ECO:0000255|HAMAP-Rule:MF_03048}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03048}.
CC   -!- PTM: C-terminal thiocarboxylation occurs in 2 steps, it is first acyl-
CC       adenylated (-COAMP) via the hesA/moeB/thiF part of UBA4, then
CC       thiocarboxylated (-COSH) via the rhodanese domain of UBA4.
CC       {ECO:0000255|HAMAP-Rule:MF_03048}.
CC   -!- SIMILARITY: Belongs to the URM1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03048}.
