Descripción general
Research area: Apoptosis. Azurinis a periplasmic protein and is a homotetramer.[1]
Aplicación
Acciones bioquímicas o fisiológicas
Azurin acts as an electron donor for nitrite reductase in bacterial denitrification process.[1] It exhibits anticancer activity[1] 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.[5]
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.

The resolution of multidimensional NMR spectra can be severely limited when regular sampling based on the Nyquist-Shannon theorem is used. The theorem binds the sampling rate with a bandwidth of a sampled signal and thus implicitly creates a dependence between
