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 MOCS3. The sulfur
CC       is then transferred to tRNA to form 2-thiolation of mcm(5)S(2)U. Also
CC       acts as a ubiquitin-like protein (UBL) that is covalently conjugated
CC       via an isopeptide bond to lysine residues of target proteins. The
CC       thiocarboxylated form serves as substrate for conjugation and oxidative
CC       stress specifically induces the formation of UBL-protein conjugates.
CC       {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 the MOCS3 homolog,
CC       then thiocarboxylated (-COSH) via the rhodanese domain of the MOCS3
CC       homolog. {ECO:0000255|HAMAP-Rule:MF_03048}.
CC   -!- SIMILARITY: Belongs to the URM1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03048}.
