CC   -!- FUNCTION: Required for disulfide bond formation in some proteins. Part
CC       of a redox system composed of DsbI and DsbL that mediates formation of
CC       an essential disulfide bond in AssT. {ECO:0000255|HAMAP-Rule:MF_01311}.
CC   -!- SUBUNIT: Interacts with DsbL. {ECO:0000255|HAMAP-Rule:MF_01311}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01311}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01311}.
CC   -!- SIMILARITY: Belongs to the DsbB family. DsbI subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01311}.
CC   -!- CAUTION: Was originally given the gene name dsbB; however another gene
CC       encoding a dsbB more closely related to that of the characterized
CC       E.coli protein bears this gene name (DSBB_SALTY, AC Q8XG65).
CC       {ECO:0000305}.
