Direct visualization of the small hydrophobic protein of human respiratory syncytial virus reveals the structural basis for membrane permeability.

abstract：:Cytochrome bd is a bacterial respiratory oxidase carrying three hemes but no copper. We show that nitric oxide (NO) reacts with the intermediate F of cytochrome bd from Azotobacter vinelandii: (i) with a 1:1 stoichiometry, (ii) rapidly (k=1.2 +/- 0.1 x 10(5)M(-1)s(-1) at 20 degrees C), and (iii) yielding the oxidized ...

This effect is not seen with azide, or when cyanide is added to ferromyoglobin-CO. It is proposed that cyanide binds to CuB, and restricts the passage of CO out of the protein. This restriction favors g...
