Fe-catalyzed cleavage of the α subunit of Na/K-ATPase: Evidence for conformation-sensitive interactions between cytoplasmic domains

Incubation of Na/K-ATPase with ascorbate plus H(2)O(2) produces specific cleavage of the α subunit. Five fragments with intact C termini and complementary fragments with intact N termini were observed. The β subunit is not cleaved. Cleavages depend on the presence of contaminant or added Fe(2+) ions...
