Journal ArticleDOI
The water- and salt-stress-regulated Asr1 (abscisic acid stress ripening) gene encodes a zinc-dependent DNA-binding protein
TL;DR: Tomato ASR1, overexpressed in Escherichia coli and purified to homogeneity, possesses zinc-dependent DNA-binding activity and competitive-binding experiments and SELEX (systematic evolution of ligands by exponential enrichment) analysis suggest that ASR 1 binds at a preferred DNA sequence.
Journal ArticleDOI
Over‐expression of the water and salt stress‐regulated Asr1 gene confers an increased salt tolerance
TL;DR: Steady-state levels of tomato Asr1 mRNA and protein are transiently increased following exposure of plants to poly- ethylene glycol, NaCl or abscisic acid, and ASR1 is probably involved in the regulation of water- or salt-stress-modulated gene expression.
Journal ArticleDOI
Desiccation and Zinc Binding Induce Transition of Tomato Abscisic Acid Stress Ripening 1, a Water Stress- and Salt Stress-Regulated Plant-Specific Protein, from Unfolded to Folded State
Yehuda Goldgur,Slava Rom,Rodolfo Ghirlando,Doron Shkolnik,Natalia Shadrin,Zvia Konrad,Dudy Bar-Zvi +6 more
TL;DR: The degree of order of ASR1 was determined experimentally using nontagged recombinant protein expressed in Escherichia coli and purified to homogeneity using Fourier transform infrared spectrometry and microcalorimetry, concomitant with dimerization.
Journal ArticleDOI
Synergism between the chaperone-like activity of the stress regulated ASR1 protein and the osmolyte glycine-betaine
Zvia Konrad,Dudy Bar-Zvi +1 more
TL;DR: It is suggested that the cytosolic pool of ASR1 protects proteins from denaturation, and the unstructured form of SlASR1 has chaperone-like activity and can stabilize a number of proteins against denaturation caused by heat and freeze-thaw cycles.
Journal ArticleDOI
Distinct glycan-charged phosphodolichol carriers are required for the assembly of the pentasaccharide N-linked to the Haloferax volcanii S-layer glycoprotein.
TL;DR: First evidence that in Archaea, as in Eukarya, the oligosaccharides N‐linked to glycoproteins are sequentially assembled from glycans originating from distinct phosphodolichol carriers is found.
