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 ...

Detergent effect on cytochrome b559 electron paramagnetic resonance signals in the photosystem II reaction centre
(Wiley, 2003)
Detergent effect on Cytochrome b559 from spinach photosystem II was studied by electron paramagnetic resonance (EPR) spectroscopy in D1-D2-Cyt b559 complex preparations. Various n-dodecyl-β-D-maltoside ...

A gibberellin-induced nuclease is localized in the nucleus of wheat aleurone cells undergoing programmed cell death
(The American Society for Biochemistry and Molecular Biology, 2003)
The aleurone layer of cereal grains undergoes a gibberellin-regulated process of programmed cell death (PCD) following germination. We have applied a combination of ultrastructural and biochemical approaches to analyze ...

A comprehensive analysis of the peroxiredoxin reduction system in the Cyanobacterium Synechocystis sp. strain PCC 6803 reveals that all five peroxiredoxins are thioredoxin dependent
(2009)
Cyanobacteria perform oxygenic photosynthesis, which gives rise to the continuous production of reactive oxygen species, such as superoxide anion radicals and hydrogen peroxide, particularly under unfavorable growth ...

Conditional Expression of RNase P in the CyanobacteriumSynechocystis sp. PCC6803 Allows Detection of Precursor RNAs
(Elsevier, 2001)
We have constructed a strain (CT1) that expresses RNase P conditionally with the aim to analyze the in vivotRNA processing pathway and the biological role that RNase P plays inSynechocystis 6803. In this strain, the rnpBgene, ...

An evolutionary analysis of the reaction mechanisms of photosystem I reduction by cytochrome c6 and plastocyanin
(Elsevier, 2002)
Photosystem I reduction by the soluble metalloproteins cytochrome c6 and plastocyanin, which are alternatively synthesized by some photosynthetic organisms depending on the relative availability of copper and iron, has ...

All4312, an NtcA-regulated two-component response regulator in Anabaena sp. strain PCC 7120
(Blackwell Publishing, 2006)
All4312, encoded by open reading frame all4312 in the genome of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120, exhibits a CheY-like receiver domain and an output domain similar to that of OmpR, ...

Generation, annotation and analysis of ESTs from Trichoderma harzianum CECT 2413
(BioMed Central, 2006)
Background: The filamentous fungus Trichoderma harzianum is used as biological control agent of several plant-pathogenic fungi. In order to study the genome of this fungus, a functional genomics project called "TrichoEST" ...
