CC   -!- FUNCTION: Required for disulfide bond formation in some periplasmic
CC       proteins. Acts by oxidizing the DsbA protein. {ECO:0000255|HAMAP-
CC       Rule:MF_00286}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00286}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00286}.
CC   -!- SIMILARITY: Belongs to the DsbB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00286}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAM09020.1; Type=Erroneous initiation; Evidence={ECO:0000305};
