ChIP analysis unravels an exceptionally wide distribution of DNA binding sites for the NtcA transcription factor in a heterocyst-forming cyanobacterium
(BioMed Central, 2014)
Background The CRP-family transcription factor NtcA, universally found in cyanobacteria, was initially discovered as a regulator operating N control. It responds to the N regime signaled by the internal 2-oxoglutarate ...

Molecular cloning and biochemical characterization of three phosphoglycerate kinase isoforms from developing sunflower (Helianthus annuus L.) seeds
(Elsevier, 2012)
Three cDNAs encoding different phosphoglycerate kinase (PGK, EC 2.7.2.3) isoforms, two cytosolic (HacPGK1 and HacPGK2) and one plastidic (HapPGK), were cloned and characterized from developing sunflower (Helianthus annuus ...

The restriction endonuclease Tru9I is a useful tool to analyze telomere sequences separately from interstitial telomeric sequences in Arabidopsis thaliana
(Scientific Research Publishing, 2012)
We have previously described a simple method to analyze the chromatin structure of Arabidopsis te- lomeres independently of that of Interstitial Telome- ric Sequences (ITSs). By using this method, we found that, whereas ...

Diverse roles of the GlcP glucose permease in free-living and symbiotic cyanobacteria
(Landes Bioscience, 2013)
Certain cyanobacteria can form symbiotic associations with plants, where the symbiont supplies the plant partner with nitrogen and in return obtains sugars. We recently showed that in the symbiotic cyanobacterium Nostoc ...

Mitochondrial Sulfide Detoxification Requires a Functional Isoform O-Acetylserine(thiol)lyase C in Arabidopsis thaliana
(Oxford University Press, 2012)
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolised by the β-Cyanoalanine ...

The cytochrome f–plastocyanin complex as a model to study transient interactions between redox proteins
(Wiley, 2012)
Transient complexes, with a lifetime ranging between microseconds and seconds, are essential forbiochemical reactions requiring a fast turnover. That is the case of the interactions between proteinsengaged in electron ...

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen
(American Society of Plant Biologists, 2012)
Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity. In contrast with OAS-B, ...

Structural and Functional Analysis of Novel Human Cytochrome c Targets in Apoptosis
(American Society for Biochemistry and Molecular Biology, 2014)
Since the first description of apoptosis four decades ago, great efforts have been made to elucidate, both in vivo and in vitro, the molecular mechanisms involved in its regulation. Although the role of cytochrome c during ...

Molecular recognition in the interaction of chloroplast 2-Cys peroxiredoxin with NADPH-thioredoxin reductase C (NTRC) and thioredoxin x
(Elsevier, 2014)
In addition to the standard NADPH thioredoxin reductases (NTRs), plants hold a plastidic NTR (NTRC), with a thioredoxin module fused at the C-terminus. NTRC is an efficient reductant of 2-Cys peroxiredoxins (2-Cys Prxs). ...

An intermolecular disulfide-based light switch for chloroplast psbD gene expression in Chlamydomonas reinhardtii
(Taylor & Francis, 2012)
Expression of the chloroplast psbD gene encoding the D2 protein of the photosystem II reaction center is regulated by light. In the green alga Chlamydomonas reinhardtii, D2 synthesis requires a high-molecular-weight complex ...
