Abstract

Summary: The soluble cytochrome oxidase/nitrite reductase of , induced under low O tensions, has a high affinity for O. EPR spectroscopy indicates that this enzyme contains 'type I' ('blue') and ('type II') Cu-sites, and UV/visible spectroscopy suggests the presence of a ('type III') Cu-pair. The enzyme binds exogenous copper in an unusual way, resulting in modified EPR spectra and a very high ε for the 'blue' 598 nm absorption band when low levels of Cu (10 μM) are present during purification.
