Enhancement of Solubility and Specific Activity of a Cu/Zn Superoxide Dismutase by Co-expression with a Copper Chaperone in Escherichia coli
Background: Human Cu/Zn superoxide dismutase (hSOD1) is an antioxidant enzyme with potential as a therapeutic agent. However, heterologous expression of hSOD1 has remained an issue due to Cu2+ insufficiency at protein active site, leading to low solubility and enzymatic activity.Objectives:The effect of co-expressed human copper chaperone (hCCS) to enhance the solubility and enzymatic act...
متن کاملCopper stabilizes the Menkes copper-transporting ATPase (Atp7a) protein expressed in rat intestinal epithelial cells.
Iron deficiency decreases oxygen tension in the intestinal mucosa, leading to stabilization of hypoxia-inducible transcription factor 2α (Hif2α) and subsequent upregulation of genes involved in iron transport [e.g., divalent metal transporter (Dmt1) and ferroportin 1 (Fpn1)]. Iron deprivation also alters copper homeostasis, reflected by copper accumulation in the intestinal epithelium and induc...
متن کاملKnock down of Caenorhabditis elegans cutc-1 exacerbates the sensitivity toward high levels of copper.
Copper, though toxic in excess, is an essential trace element that serves as a cofactor in many critical biological processes such as respiration, iron transport, and oxidative stress protection. To maintain this balance between requirement and toxicity, biological systems have developed intricate systems allowing the preservation of homeostasis while ensuring delivery of copper to the appropri...
متن کاملCopper-Dependent Trafficking of the Ctr4-Ctr5 Copper Transporting Complex
BACKGROUND In Schizosaccharomyces pombe, copper uptake is carried out by a heteromeric complex formed by the Ctr4 and Ctr5 proteins. Copper-induced differential subcellular localization may play a critical role with respect to fine tuning the number of Ctr4 and Ctr5 molecules at the cell surface. METHODOLOGY/PRINCIPAL FINDINGS We have developed a bimolecular fluorescence complementation (BiFC...
متن کاملToxicity of binary mixtures of cadmium-copper and carbendazim-copper to the nematode Caenorhabditis elegans.
For ecological risk assessment, the additive model may be used to empirically predict toxic mixture effects. Detailed toxicity tests were performed to determine whether effects of mixtures of copper-cadmium and copper-carbendazim on Caenorhabditis elegans were similar to the effects of the individual compounds. Effects on the course of reproduction, the length of the juvenile period, the length...
