Figure 2From: The FtsH protease is required for the repair of Photosystem II in the cyanbacterium Synechocystis6803 damaged UV-B radiationUV-B induced loss, and recovery of oxygen evolution. The time course of oxygen evolution was followed in the WT (circles) and MFtsH cells (up triangles) during exposure to UV-B light and subsequent recovery in low intensity (40 MEm-2s-1) visible light. The time course of oxygen evolution is also shown in the presence of lincomycin for the WT cells (down triangles)Back to article page
