DE   [DsrC]-trisulfide reductase.
CA   [DsrC protein]-dithiol + 2 a quinone + hydrogen sulfide + H(+) =
CA   [DsrC protein]-trisulfide + 2 a quinol.
CC   -!- This enzyme complex is present in both sulfate-reducing bacteria and
CC       sulfur-oxidizing bacteria, and acts in opposite directions during the
CC       reductive and oxidative pathways, respectively.
CC   -!- DsrM and DsrP contain b-type hemes, DsrJ contains c-type hemes, DsrO
CC       is a ferredoxin-like protein, and DsrK is the catalytic subunit that
CC       acts as a disulfide reductase on DsrC proteins that contain a
CC       trisulfide bridge.
CC   -!- The complex receives the electrons from the membrane quinone pool.
