Abstract
Sixteen low temperature measurements on eight independent cytochrome oxidase samples from two separate laboratories have yielded magnetic susceptibility data compatible with a model of spin-coupled iron and copper ions, as presented in the preceding paper (Tweedle, M.F., Wilson, L.J., García-Iñiguez, L., Babcock, G. T., and Palmer, G. (1978) J. Biol. Chem. 253, 8065-8071). The data in the 1.5-77 K range match those attained at higher temperatures and the predictions of the spin-coupled model. Measurements on reduced samples confirm the high spin nature of one iron atom. No obvious uncoupling of the antiferromagnetic Fe-Cu interaction is detected in partly reduced samples.Entities:
