摘要：

Copper-containing nitrite reductase isolated from Hyphomicrobium sp. A 3151 has been characterized by electronic absorption, circular dichroism (CD) and electron paramagnetic resonance (EPR) spectroscopies. The visible absorption spectrum of Type I copper (blue copper) in the enzyme especially indicates novel features compared with those of Type I coppers in not only several nitrite reductases already reported but also small blue copper proteins. The EPR spectrum of Type I copper exhibits an axial symmetry.
