== Function == | |||
[https://www.uniprot.org/uniprot/SQRD_ACIAM SQRD_ACIAM] Catalyzes the oxidation of sulfides, such as hydrogen sulfide, with the help of a quinone. Has the highest activity with caldariella quinone and decylubiquinone, and lower activity with naphtoquinones. 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:19438211</ref> | |||
