Mutation-induced perturbation of the special pair P840 in the homodimeric reaction center in green sulfur bacteria.

Scientific reports - 25 Jan 2016

Abstract excerpt

Homodimeric photosynthetic reaction centers (RCs) in green sulfur bacteria and heliobacteria are functional homologs of Photosystem (PS) I in oxygenic phototrophs. They show unique features in their electron transfer reactions; however, detailed structural information has not been available so far. We mutated PscA-Leu688 and PscA-Val689 to cysteine residues in the green sulfur bacterium Chlorobaculum tepidum;...
