Application

Rhodanese (RHOD) is an enzyme that converts cyanide to thiocyanate. RHOD may be useful in ulcerative colitis (UC) research as it has been shown to have detoxifying properties in the colon . Rhodanese is used to study sulfur energy metabolism .

Biochem/physiol Actions

Rhodanese (RHOD) is the principal enzyme involved in hydrogen sulphide (H2S) detoxication in the colonic luman .

Unit Definition

One unit will convert 1.0 μmole of cyanide to thiocyanate per min at pH 8.6 at 25°C.

Rhodanese-domain proteins (RDPs) are widespread in plants and other organisms, but their biological roles are mostly unknown. Here we report on a novel RDP from Chlamydomonas that has a single rhodanese domain, and a predicted chloroplast transit peptide. The protein

Defective detoxification of sulfides leads to damage to the mucosa and may play a role in the etiology of ulcerative colitis (UC). The colonic mucosal thiosulfate sulfurtransferase (TST) enzyme removes H(2) S by conversion to the less toxic thiocyanate. In

The chaperonin GroEL binds to non-native substrate proteins via hydrophobic interactions, preventing their aggregation, which is minimized at low temperatures. In the present study, we investigated the refolding of urea-denatured rhodanese at low temperatures, in the presence of ox-GroEL (oxidized
