CC   -!- FUNCTION: Thiol-disulfide oxidoreductase which is required in disulfide
CC       reduction during c-type cytochrome synthesis. May accept reducing
CC       equivalents from CcdA, leading to breakage of disulfide bonds in
CC       apocytochrome c; following this reduction heme can be covalently
CC       attached. {ECO:0000255|HAMAP-Rule:MF_01319}.
CC   -!- PATHWAY: Protein modification; cytochrome c assembly.
CC       {ECO:0000255|HAMAP-Rule:MF_01319}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01319};
CC       Single-pass type II membrane protein {ECO:0000255|HAMAP-Rule:MF_01319}.
CC       Note=The thioredoxin-like motif is exposed on the outside of the
CC       membrane. {ECO:0000255|HAMAP-Rule:MF_01319}.
CC   -!- SIMILARITY: Belongs to the thioredoxin family. ResA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01319}.
