FIGURE 6.

Effect of Hsp17 mutations on oxygen evolving activity. Heat-preconditioned (42 °C, 3 h) WT (circles), Q16R (triangles), and L9P (diamonds) strains were exposed to UV-B radiation for 2 h followed by a recovery period in visible light (VIS) for 1 h. Oxygen evolving activities were measured at the indicated time points. The results are expressed as percentages of the oxygen evolution rate measured at time 0. The error bars represent standard errors obtained from three repetitions. The experiments were performed in the absence (A) or presence (B) of the protein synthesis inhibitor lincomycin.
