2. N-hydroxyguanidines as new heme ligands: UV-visible, EPR, and resonance Raman studies of the interaction of various compounds bearing a C=NOH function with microperoxidase-8

Abstract

Research has been conducted on the microperoxidase-8, a water-soluble hemeprotein model. The interactions between this microperoxidase and N-aryl and N-alkyl N'-hydroxyguanidines and related compounds have been examined via UV-visible, EPR and resonance Raman spectroscopies.

3. Remarkable ability of horse spleen apoferritin to demetallate hemin and to metallate protoporphyrin IX as a function of pH

Abstract

A spectral study of the interaction between heme and horse spleen apoferritin as a function of pH is presented. Evidence shows that not only does this protein remove iron from heme at acidic pH but it can also reincorporate iron into protoporphyrin IX at more basic pH. Chemical modification reveals that carboxyl groups are involved in heme demetallation. Results indicate that horse spleen apoferritin, as well as mammalian ferritins, have preserved their heme-binding site but have acquired the capacity to demetallate the porphyrin.

Abstract

A study explains the reactivity of the flavin of flavocytochrome [b.sub.2], a flavohemoprotein with molecular oxygen. The described process of electron transfer is found to be extremely slow and incompetent.
