The thermophilic phototroph Chloroflexus aurantiacus possesses a photosynthetic reaction center (RC) containing a pair of menaquinones acting as primary (MQa) and secondary (MQB) electron acceptors and a tetraheme cytochrome c554 as an electron donor

To study electrogenesis the photosystem I particles from Synechococcus elongatus were incorporated into asolectin liposomes, and fast kinetics of laser flash-induced electric potential difference generation has been measured by a direct electrometric

An M-type intermediate is formed in the 13- cis -bR photocycle in purple membranes at high pH. This is presumably due to deprotonation of the same group whose deprotonation causes a large increase in rate of M formation in the trans -bR photocycle (t

An electrometric method was used to investigate the effect of pH and ionic strength on the second flash-induced formation of the transmembrane electric potential difference (Δψ) arising from proton uptake by the quinone complex of the photosyntheti

The kinetics of CO reassociation with isolated Bacillus FTU o-type oxidase and with solubilized membranes of Escherichia coli (GO102 strain) containing the d-type oxidase only, upon laser flash photolysis under reducing conditions, were studied. In b

— In purple bacteriorhodopsin sheets adsorbed onto the phospholipid-impregnated collodion film, electrogenic stages are identified correlating with decays of the M and N(P)-type intermediates. It is concluded that both M → N and N → bR transiti

The photosynthetic reaction centers (RC) of the green bacterium Chloroflexus aurantiacus have been investigated by spectral and electrometrical methods. In these reaction centers, the secondary quinone was found to be reconstituted by the addition of

pH-titration of the dark-adapted 13- cis -retinal-containing bacteriorhodopsin (13- cis -bR) photocycle was performed in native and regenerated purple membranes, Triton X-100 solubilized and liposomal monomeric preparations. Under alkaline pH conditi
