| Research Abstract |
Nucleoproteins were solubilized from isolated mung bean nuclei and separated by a column of mono Q. Fractions of alpha-amanitin-sensitive RNA polymerase activity were pooled and applied to a column of auxin-binding protein-I(ABP-I)-bound Sepharose 4B. RNA polymerase activity was completely retained on the column and eluted by 0.3 M (NH_4)@>D22@>D2SO_4.
RNA polymerase II was purified from wheat germ by the method of Burgess et al. and examined an interaction for ABP-I. The purified TNA polymerase II was retained on the affinity column of ABP-I-bound Sepharose 4B and eluted by 0.3 M (NH_4)_2SO_4.
From these results, we consider that RNA polymerase II have an affinity for ABP-I and the interaction may play a role for gene expression.
