Abstract
A Mössbauer effect study was carried out on cytochrome c3 to investigate the heme-heme magnetic interaction. Results observed in the spectrum of partially reduced cytochrome c3 at 4.2 K shows that a strongly enhanced heme-heme magnetic interaction exists between cytochrome c 3 molecules.
Résumé
Nous avons étudié le cytochrome c3 par effet Mössbauer afin de déterminer l'interaction heme-heme magnétique. Nous concluons des résultats du spectre obtenu à 4,2 K sur le cytochrome c3 partiellement réduit qu'il existe une interaction magnétique heme-heme fortement augmentée.
