CC   -!- FUNCTION: Required to facilitate the formation of correct disulfide
CC       bonds in some periplasmic proteins and for the assembly of the
CC       periplasmic c-type cytochromes. Acts by transferring electrons from
CC       cytoplasmic thioredoxin to the periplasm. This transfer involves a
CC       cascade of disulfide bond formation and reduction steps.
CC       {ECO:0000255|HAMAP-Rule:MF_00399}.
