The D1 polypeptide of photosystem II (PSII) is synthesized as a precursor that is processed by cleavage at the carboxyl terminus during assembly of the active PSII complex. A mutant of the green alga Scenedesmus obliquus, LF-1, inactive in water-spli

SpoIVB is essential for intercompartmental signalling in the sigma(K)-checkpoint of Bacillus subtilis. SpoIVB is synthesized in the spore chamber and is the signal which activates proteolytic processing of pro-sigma(K) to its mature and active form s

3-Alkyl-2-hydroxy-1,4-naphthoquinones (alkyl-HNQ) inhibit Rieske iron-sulfur cluster (Rieske FeS) oxidation and cytochrome b reduction in ubiquinol-cytochrome c oxidoreductase. The effects are the same as those of 5-undecyl-6-hydroxy-4,7-dioxobenzoth

The antimycin-sensitive ubisemiquinone radical (QC) of the ubiquinol-cytochrome c oxidoreductase of submitochondrial particles and chromatophores of Rhodopseudomonas sphaeroides Ga has been studied by a combination of redox potentiometry and EPR spec

In the LF-1 mutant of Scenedesmus obliquus, a failure to remove a C-terminal extension from the D1 protein of photosystem II (PS II) is associated with the absence of a water-splitting manganese complex. Treatment of LF-1 thylakoids and PS II-enriche
