... the rate of inhibition. Identical studies using GAPDH with samples of RNase A peroxides which had been pretreated with NaBH 4 to remove peroxides (see above), gave similar extents of inhibition ... inactivation of G APDH being metal- ion independent, whereas inhibition of GR and LDH by H 2 O 2 occurs most rapidly in the presence of metal ions. It is proposed that the inhi...
