During photosynthesis light energy is converted into energy of chemical bonds through a
series of electron and proton transfer reactions. Over the first ultrafast steps of …

Using site-directed mutagenesis, we obtained the mutant of the purple bacterium
Rhodobacter sphaeroides with Ile to His substitution at position 177 in the L-subunit of the …

This mini review presents a general comparison of structural and functional peculiarities of
three types of photosynthetic reaction centers (RCs)–photosystem (PS) II, RC from purple …

We demonstrated earlier that as a result of the I (L177) H mutation in the photosynthetic
reaction center (RC) of the bacterium Rhodobacter sphaeroides, one of the …

Histidine M182 in the reaction center (RC) of Rhodobacter sphaeroides serves as the fifth
ligand of the bacterio-chlorophyll (BChl) BB Mg atom. When this His is substituted by an …

Photosynthetic reaction center (RC) of the purple bacterium Rhodobacter sphaeroides is
one of the most well-studied transmembrane pigment-protein complexes. It is a relatively …

The first steps of the global process of photosynthesis take place in specialized membrane
pigment–protein complexes called photosynthetic reaction centers (RCs). The RC of the …

REACTION CENTER STRUCTURES 249 10 molecules (39), whereas R. viridis has one
menaquinone-9 and one ubiquinone-9 molecule (46). Various types of carotenoids are used …

Despite the: central role of membrane proteins in cellular processes, com paratively little
structural information has been available concerning the atomic details of their structural …

There is no doubt that studying the photosynthetic conversion of light into chemical energy is
extremely important in many points of view: 1) technical-in order to improve the utilization of …
