When you need to ship a package to someone at CU, consider using the CU delivery program. This program is run by The UPS Store at CU and it handles the entire process from processing to charging to delivery. You will need to register for the program and The UPS Store will contact you directly to set up your account and begin handling your packages.
CU’s home2home delivery program
CU students can take advantage of The UPS Store’s home2home delivery program by ordering packages directly from their campus. The store handles all the shipping, processing, and charging. Interested students will receive information on the program in their room assignment notification. This program is a great way to receive packages at affordable prices without having to leave campus.
Copper-dependent antioxidant activity of disulfiram
Disulfiram, an anti-alcoholism drug with a good safety profile, has also been shown to have anticancer properties in vitro and in vivo. Its PLGA-PEG nanoparticles have shown a reduction in breast cancer tumor growth rate. Disulfiram cytotoxicity is thought to be exerted in two ways: by enhancing the toxicity of chemotherapeutic drugs and by protecting normal cells from cytotoxic agents.
Disulfiram binds to copper and forms a complex with copper (DSF-Cu). DSF-Cu increases intracellular copper levels by bypassing membrane transporters and inducing oxidative stress-mediated apoptosis in tumor cells. Compared with wild-type mice, disulfiram increased copper levels in the brain.
CU Delivery NosL
The crystal structure of NosL holo-Cu has been determined to be remarkably similar to that of the apo-NosL. This difference in conformational state is due to an underlying geometrical inversion of the Cu-binding site. The ligand Met145 has been shown to undergo a major conformational rearrangement during Cu binding.
The copper-transporting protein NosL is produced by the denitrifying bacterium S. denitrificans. The isolated protein was characterized by ICP-MS and was found to contain 0.02 Cu and 0.56 Zn2+ ions per monomer. This result suggests that NosL may be reconstituted by CuI in anoxic conditions.
Physiological roles of NosL and NosD have been studied in this study. The crystal structure of NosL holoprotein will provide valuable insight into how these proteins interact. Further studies will focus on the physiological role of NosL.
CU Delivery NosD
Copper transport in bacteria requires the presence of a copper chaperone. The NosD gene carries the copper chaperone NosDFY. It is an essential element for the assembly of rNosZ, a copper transport protein. Several studies have suggested that NosDFY may also be involved in sulfur export. The isolated proteins were colorless in oxic conditions and contained reduced CuA. However, the proteins oxidized slowly in the presence of dioxygen after a several-day air exposure.
The mechanism of Cu delivery through the NosD chaperone is still unclear. The transporter system is required to carry Cu to the site of Cu cluster biosynthesis. The NosDFY ABC transporter system delivers Cu and sulfur. NosD may transport Cu to the site of Cu cluster biosynthesis via NosA or another cation-permeable pore. In this case, Cu and sulfur donation converge in the periplasm, allowing the formation of Cu-S clusters.
CU Delivery SdNosL
The crystal structure of SdNosL shows a mixed b/a topology and features two structurally similar domains. This protein contains four b-sheets and three antiparallel b-sheets. The N-terminal region of the protein is well-ordered and likely results from the coordination of two metal ions that are located near the surface of the protein.
The 18-character code is XZQ ENV NOLLV4Q90C. It also contains the oe llectees SHMUOAM AAOLOVA and IVLOL_OZLUOdTE LON WAAO. This code is used to identify the recipients.
A possible mechanism for copper delivery through SdNosL has been proposed. The interaction of NosD and neighboring monomers suggests that copper can be delivered through this molecule. The Zn-Cu site is likely to achieve a metal-loaded resting state even without a ligand. This structure also suggests that NosD is permanently anchored to the cytoplasmic membrane.
