Zusammenfassung

Zwischen der Tetramer- und der Dimer-Form der Erythrocyten-Katalase besteht ein Gleichgewicht. Dieses lässt sich in vitro durch Variation der Harnstoffkonzentration beliebig verschieben. Das dabei entstehende Dimer zeigt Peroxidase-, nicht aber Katalase-Aktivität. Bei der Reassoziation, deren Geschwindigkeit sich durch andere Proteine beeinflussen lässt, entsteht ein Produkt, das vom nativen Enzym nicht unterscheidbar ist.
