Proteolytic activity of CtpB and CtpC from lower photosynthetic organisms for pD1 processing. (A) Schematic diagrams of PpCtpB-HA or PpCtpC-HA (from P. patens), CrCtpB-HA or CrCtpC-HA (from C. reinhardtii), and SeCtpB-HA or SeCtpC-HA (from S. elongatus). AtCtpA-TP is the N-terminal chloroplast transit peptide of AtCtpA; mPpCtpB or C, mCrCtpB or C, and mSeCtpB or C are the mature proteins; 2HA is a double hemagglutinin tag. (B,C) Ectopic expression of PpCtpB-HA or PpCtpC-HA and CrCtpB-HA or CrCtpC-HA driven by the CaMV 35S promoter in atctpa was analyzed as described in the legend of Figure 7. (D,E) In vitro protease activity of PpCtpB or C and CrCtpB or C were assayed with recombinant AtpD1 as substrate as described in the legend of Figure 4.
