Protein Dynamics Control of Electron Transfer in Photosynthetic Reaction Centers from Rps. Sulfoviridis
(American Chemical Society, 2008)
In the cycle of photosynthetic reaction centers, the initially oxidized special pair of bacteriochlorophyll molecules is subsequently reduced by an electron transferred over a chain of four hemes of the complex. Here, we ...

Sequence-dependent cleavage site selection by RNase Z from the cyanobacterium synechocystis sp. PCC 6803
(Elsevier, 2005)
Biosynthesis of transfer RNA requires processing from longer precursors at the 5′- and 3′-ends. In eukaryotes, in archaea, and in those bacteria where the 3′-terminal CCA sequence is not encoded, 3′ processing is carried ...

The sequence selectivity of KSRP explains its flexibility in the recognition of the RNA targets
(Oxford University Press, 2008)
K-homology (KH) splicing regulator protein (KSRP) is a multi-domain RNA-binding protein that regulates different steps of mRNA metabolism, from mRNA splicing to mRNA decay, interacting with a broad range of RNA sequences. ...

The Efficient Functioning of Photosynthesis and Respiration in Synechocystis sp. PCC 6803 Strictly Requires the Presence of either Cytochrome c6 or Plastocyanin
(Elsevier, 2004)
In cyanobacteria, cytochrome c6 and plastocyanin are able to replace each other as redox carriers in the photosynthetic and respiratory electron transport chains with the synthesis of one or another protein being regulated ...

Structure of the Complex between Plastocyanin and Cytochrome f from the Cyanobacterium Nostoc sp. PCC 7119 as Determined by Paramagnetic NMR
(Elsevier, 2005)
The complex between cytochrome f and plastocyanin from the cyanobacterium Nostoc has been characterized by NMR spectroscopy. The binding constant is 16 mm–1, and the lifetime of the complex is much less than 10 ms. ...

Changes in photosynthetic electron transfer and state transitions in an herbicide-resistant D1 mutant from soybean cell cultures
(Elsevier, 2007)
Anomalies in photosynthetic activity of the soybean cell line STR7, carrying a single mutation (S268P) in the chloroplastic gene psbA that codes for the D1 protein of the photosystem II, have been examined using different ...

Phosphorylation-mediated unfolding of a KH domain regulates KSRP localization via 14-3-3 binding
(Nature Research, 2009)
The AU-rich element (ARE)-mediated mRNA-degradation activity of the RNA binding K-homology splicing regulator protein (KSRP) is regulated by phosphorylation of a serine within its N-terminal KH domain (KH1). In the cell, ...

Mutual dependence of the expression of the cell differentiation regulatory protein HetR and the global nitrogen regulator NtcA during heterocyst development
(Wiley, 2002)
Heterocyst differentiation in the cyanobacterium Anabaena sp. strain PCC 7120 depends on both the global nitrogen regulator NtcA and the cell differentiation regulatory protein HetR, and induction of hetR upon nitrogen ...

NMR analysis of the transient complex between membrane photosystem I and soluble cytochrome c6
(Elsevier, 2005)
A structural analysis of the surface areas of cytochrome c6, responsible for the transient interaction with photosystem I, was performed by NMR transverse relaxation-optimized spectroscopy. The hemeprotein was titrated by ...
