摘要：

An electron spin echo-detected electron paramagnetic resonance study has been performed on the type-2 copper site of the nitrite reductase from Alcaligenes faecalis. The experiment on a single crystal at 95 GHz has allowed the determination of the complete g tensor. This includes the orientations of the principal axes of three g tensors in the asymmetric unit of the unit cell with respect to the crystallographic axes. The orientation with respect to the crystallographic axes has been translated into the orientation of the g tensor in the type-2 copper site. The corresponding electronic structure is discussed in relation to the enzymatic function of this copper site.
