rhodanese, n. Biochem.|ˈrəʊdəniːz|
Also rhodanase |-eɪz|.
[a. G. Rhodanese (K. Lang 1933, in Biochem. Zeitschr. CCLIX. 246), f. Rhodan thiocyanogen: cf. -ase.]
A naturally occurring enzyme, also called thiosulphate sulphurtransferase, which catalyses the formation of thiocyanate and sulphite from thiosulphate and cyanide radicals.
1933Chem. Abstr. XXVII. 5349 There is present in the organism an enzyme rhodanese which brings about the union of S with HCN. 1945Arch. Biochem. VII. 459 The Schütz rule does not apply to the reaction catalyzed by rhodanese, since the ml. of rhodanate formed divided by the square root of the ml. of rhodanese solution used do not give a constant value. 1968A. White et al. Princ. Biochem. (ed. 4) XXVI. 598 Liver contains rhodanese, a sulfhydryl-containing enzyme which promotes formation of thiocyanate from CN- and S2O3{b2}. 1978Nature 11 May 124/1 Rhodanese..is..widely distributed in nature and especially abundant in mammalian liver and kidney. 1987Oxf. Textbk. Med. (ed. 2) I. vi. 56/2 The principal route of detoxification of cyanide in the body is by conversion to thiocyanate by rhodanase, an enzyme present in liver and muscle. |
