CC   -!- FUNCTION: Required for formate dehydrogenase (FDH) activity. Acts as a
CC       sulfur carrier protein that transfers sulfur from IscS to the
CC       molybdenum cofactor prior to its insertion into FDH.
CC       {ECO:0000255|HAMAP-Rule:MF_00187}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00187}.
CC   -!- SIMILARITY: Belongs to the FdhD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00187}.
