Structure and Function of the Homodimeric Reaction Center, and Hydrogen Production, in Heliobacterium modesticaldum


Abstract The evolution of photosynthesis caused the oxygen-rich atmosphere in which we thrive today. Although the reaction centers involved in oxygenic photosynthesis probably evolved from a protein like the reaction centers in modern anoxygenic photosynthesis, modern anoxygenic reaction centers are poorly understood. One such anaerobic reaction center is found in Heliobacterium modesticaldum. Here, the photosynthetic properties of H. modesticaldum are investigated, especially as they pertain to its unique photochemical reaction center.

The first part of this dissertation describes the optimization of the previously established protocol for the H. modesticaldum reaction center isolation. Subsequently, electron transfer is characterized by ultrafast... (more)
