(A) Crude cell extracts from barley, both WT and Xantha-hclo 157, were assayed for magnesium chelatase activity. Xantha-hclo 157 extracts alone had no activity, and they inhibited the activity of the WT when they were mixed. (B) Purified magnesium chelatase subunits from R. capsulatus were assayed for magnesium chelatase activity. WT BchH and BchD subunits were in all assays with various combinations of WT and modified BchI. The numbers in the legend indicate the relative amount of BchI (1 corresponds to 2.5 μg, and 2 corresponds to 5 μg). Symbols were added to identify the curves.
