    Notes: Summary Antisera against chromogranin A, B and C were used to study the distribution of these acidic proteins in bovine endocrine and nervous tissues. The three chromogranins occur together in several endocrine organs (adrenal medulla, anterior pituitary, endocrine pancreas) and in sympathetic ganglion cells. In the posterior pituitary, only chromogranin C and in the intermediate lobe only A and C are found. The parathyroid gland contains only A, and enterochromaffin cells are immunoreactive for A and B. Cells of the thyroid gland and some cells of the anterior pituitary apparently do not contain any chromogranins. It is concluded that the three chromogranins are not always stored together and that they are not present in all endocrine cells. This distinct localization of the chromogranins indicates some special, although still undiscovered, function for these proteins.

    Paramagnetic relaxation in high-spin ferrous compounds (1986)
    Springer
    Hyperfine interactions 29 (1986), S. 1347-1350

    Notes: Abstract Measurements of three high-spin FeIIS4 complexes at various temperatures and applied magnetic fields are reported and the results are compared with those of reduced rubredoxin. Simulations of the measured spectra by means of the fully developed stochastic theory of lineshape prove that intermediate relaxation behavior is present and is determined essentially by the phonon energy distribution and by one single parameter W0, the scaling factor, which contains the strength of spin-lattice coupling.

    Evidence for dynamic behavior of O2 in oxyheme model compounds (1986)
    Springer

    Notes: Abstract We have performed Mössbauer studies on several oxy-heme model compounds, and for two of them we also have derived the threedimensional structure from X-ray studies; I: [Fe(O2) (SC6HF4) TPpivP] [Na⊂18C6] and II: [Fe(O2) (SC6HF4)TPpivP] [K⊂222]. Compound I shows a pronounced temperature-dependence of ΔEQ, i. e. 2.17 mms−1 at 4.2 K and 1.55 mms−1 at 295 K, while ΔEQ of compound II is practically temperature-independent, i.e. ca. 2.05 mms−1. The X-ray structure analysis of these model compounds provides us with the fact that O2 occupies three different sites in I and only two sites in II. From the experimentally known occupancies of these sites at specific temperatures we were able to apply relaxation calculations for the electric field gradient tensors in I and II, and we found for both compounds that our calculated ΔEQ(T)-data are in agreement with our experimental results. These findings imply that the dynamic jump behavior of O2 among the different sites in oxy-heme model compounds is responsible for the temperature-dependence (like in HbO2) or temperature-independence of ΔEQ (like in cytochrome P450).
