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}.
