However, the underpinning molecular and biochemical mechanisms remain unknown. In this study, we reveal that a previously unidentified Rieske-type protein is
The conserved protein lifespan KRI-1 is required for DAF-16/FoxO nuclear transloca- tion in animals lacking a germline but largely dispensable DAF-16/FoxO is required for C. elegans lifespan for DAF-16/FoxO nuclear localization in animals with modulation by IIS and the germline [1, 2], as well as in reduced IIS . Frontiers Eion, Purification, Refolding, and Oct 21, 2020 · The reaction can be catalyzed by the evolutionarily conserved Rieske-domain oxygenase neverland (NVD), which contains a Rieske [2Fe2S] cluster binding domain to function as an electron acceptor and electron transfer, and a highly conserved non-heme iron-binding center as a catalytic domain (Yoshiyama et al., 2006).

"The Sterol-C7 desaturase from the ciliate Tetrahymena thermophila is a Rieske Oxygenase, which is highly conserved in animals." Mol Biol Evol 30(7);1630-43. PMID:23603937 Sterol-C7 Desaturase from the Ciliate Tetrahymena Apr 19, 2013 · This work reports the identification of a Rieske [2Fe-2S] oxygenase, belonging to the Nvd/DAF-36 family of proteins, as the sterol C7(8)-desaturase of T. thermophila. Furthermore, we provide strong phylogenetic evidence showing that this family of proteins is evolutionarily conserved not only in animals but also in ciliates of the clade

Jan 04, 2017 · Rieske non-heme iron oxygenases, which have a Rieske-type [2Fe2S] cluster and a non-heme catalytic iron center, are an important family of oxidoreductases involved mainly in regio- and stereoselective transformation of a wide array of aromatic hydrocarbons. Though present in all domains of life, the most widely studied Rieske non-heme iron oxygenases are daf-36 - Cholesterol 7-desaturase - Caenorhabditis elegans Oct 01, 2003 · Catalyzes the production of 7-dehydrocholesterol (7-DHC) by the desaturation of the C7-C8 single bond of cholesterol. This reaction is the first step in the synthesis of the steroid hormone Delta(7)-dafachronic acid. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth.
