RL Submitted (AUG-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: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
