CC   -!- FUNCTION: Part of a sulfur-relay system required for 2-thiolation of 5-
CC       methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at tRNA wobble positions.
CC       Accepts sulfur from TusA and transfers it in turn to TusE.
CC       {ECO:0000255|HAMAP-Rule:MF_00390}.
CC   -!- SUBUNIT: Heterohexamer, formed by a dimer of trimers. The hexameric
CC       TusBCD complex contains 2 copies each of TusB, TusC and TusD. The
CC       TusBCD complex interacts with TusE. {ECO:0000255|HAMAP-Rule:MF_00390}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00390}.
CC   -!- SIMILARITY: Belongs to the DsrE/TusD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00390}.
