General Information

General Information Comment Organism
additional information structure modeling of cysteine dioxygenase in complex with L-cysteine dianion Rattus norvegicus
additional information the structure of CDO, which is highly conserved across multiple species, is built on a small alpha-helical domain containing three alpha-helices at the N-terminus, followed by 13 beta-strands. These are subdivided into a main beta-sandwich domain and two beta-hairpins at the C terminus. The entire beta-sandwich is composed of seven anti-parallel beta-strands on the lower side and six anti-parallel beta-strands on the upper side. The active site comprises an iron ion, which is located in the central portion of the cupin beta-sandwhich, and is connected to the bulk solvent through a solvent-filled channel Rattus norvegicus
physiological function in the ferrous form, CDO catalyzes irreversibly the conversion of cysteine to cysteine sulfinate, incorporating both atoms of dioxygen into the product. Cysteine sulfinate is an intermediate of several pathways related to pyruvate and sulfurated metabolites, such as sulfate, taurine, and hypotaurine. The CDO performance increases in response to high cysteine levels,either through the formation of a C93-Y157 crosslink, or a diminished degradation by the ubiquitin-proteasome system Rattus norvegicus
