The homospermidine synthases from P. aeruginosa and B. viridis, as well as their single-residue variants, are compared based on crystal structures and activity assays. A high structural similarity is demonstrated, suggesting the equivalent involvemen

Publikováno v: NATURE

The light-harvesting 1–reaction centre (LH1–RC) complex is a key functional component of bacterial photosynthesis. Here we present a 2.9 Å resolution cryo-electron microscopy structure of the bacteriochlorophyll b-based LH1–RC complex from Bla

Redox potentials of ubiquinone, menaquinone, phylloquinone, and plastoquinone in aqueous solution

Autor: Keisuke Saito, Yuki Kato, Hiroshi Ishikita, Shinnosuke Kishi

Publikováno v: Photosynthesis Research

Quinones serve as redox active cofactors in bacterial photosynthetic reaction centers: photosystem I, photosystem II, cytochrome bc 1, and cytochrome b 6 f. In particular, ubiquinone is ubiquitous in animals and most bacteria and plays a key role in
