A non‐blue copper‐containing glycoprotein was isolated from Pseudomonas aeruginosa . The protein has a molecular mass of 10 kDa and contains 1 atom of EPR‐detectable type II copper. The protein inhibits oxidation of both azurin and cytochrome c ‐551 catalyzed by nitrite reductase from Ps. aeruginosa . Thus, it may be considered as an endogenous inhibitor of nitrite reductase.
