== Function == | |||
[https://www.uniprot.org/uniprot/SQRD_ACIF2 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.<ref>PMID:20303979</ref> <ref>PMID:22542586</ref> | |||
