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}.
