Fig. 3. cAMP–CRP activation of deoP2 with RNP carrying intact α (α-WT) (37 nM), α with 256 amino acids (α-256) (150 nM) or with 235 amino acids (α-235) (150 nM). In the same reaction tube was also added 2 nM lacZp DNA. cAMP was present at 0.1 mM in all lanes and CRP (0.1 µM) was present only in the even-numbered lanes.
