RT   "Genetically similar prophage deferentially affect host competitiveness.";
RL   Submitted (MAR-2018) to the EMBL/GenBank/DDBJ databases.
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:0000256|HAMAP-Rule:MF_00187}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00187}.
CC   -!- SIMILARITY: Belongs to the FdhD family. {ECO:0000256|HAMAP-
CC       Rule:MF_00187}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC       feature annotation. {ECO:0000256|HAMAP-Rule:MF_00187}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
CC       {ECO:0000313|EMBL:PTA99804.1}.
