General description

Research area: Apoptosis. Azurinis a periplasmic protein and is a homotetramer.

Application

Azurin has been used:
  • in the cytotoxicity and cell viability studies in human osteosarcoma cell line
  • for the functionalization of silicon nitride cantilevers for interaction studies
  • for coating gold surface and insulating functionalized oxide surfaces of silicon oxide and mica

Biochem/physiol Actions

Azurin acts as an electron donor for nitrite reductase in bacterial denitrification process. It exhibits anticancer activity as it hampers various independent signaling pathways associated with cancer progression. It binds to tumor suppressor protein p53 and induces cancer cell apoptosis or stalls cancer cell growth. Azurin disrupts angiogenesis by reducing the activity of VEGFR-2tyrosine kinase thereby inhibiting tumor growth. It has been observed to show cytotoxicity in human breast cancer cells and human melanoma cells.
Azurin is a metalloprotein in the family of cupredoxins. It preferentially enters cancer cells over normal cells and induces apoptosis. Azurin has structural similarities to ephrinB2, and in fact binds the ephrin receptor tyrosine kinase EphB2 to initiate cell signaling that is involved in cancer progression. Azurin inhibits autophosphorlyation of the EphB2 tyrosine residue, interfering with upstream cell signaling and contributing to cancer cell growth inhibition.

Pseudoazurin (PAz), a well-characterized blue copper electron-transfer protein, is shown herein to be capable of mediating electron transfer to the nitrous oxide reductase (N(2)OR) from Achromobacter cycloclastes (Ac). Spectroscopic measurements demonstrate that reduced PAz is efficiently re-oxidized by a catalytic

Many biological electron-transfer reactions involve short-lived tryptophan radicals as key reactive intermediates. While these species are difficult to investigate, the recent photogeneration of a long-lived neutral tryptophan radical in two Pseudomonas aeruginosa azurin mutants (Az48W and ReAz108W) made it possible

Measuring solid-state electron transport (ETp) across proteins allows studying electron transfer (ET) mechanism(s), while minimizing solvation effects on the process. ETp is, however, sensitive to any static (conformational) or dynamic (vibrational) changes in the protein. Our macroscopic measurements allow extending

Azurin secreted by Pseudomonas aeruginosa is an anticancer bacteriocin, which preferentially enters human cancer cells and induces apoptosis or growth inhibition. It turns out that azurin is a multi-target anticancer agent interfering in the p53 signaling pathway and the non-receptor
