This structure supersedes the now removed PDB entry 3kpg. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.2999Å Ligands: DCQ, FAD, H2S, LMT Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function SQRD_ACIF2 Catalyzes the oxidation of hydrogen sulfide, with the help of a quinone. Consecutive reaction cycles lead to the accumulation of a polysulfide product on the active site Cys residues; these products are released when they exceed a critical length, typically as cyclooctasulfur.
