Hydrogen sulfide generated by L-cysteine desulfhydrase acts upstream of nitric oxide to modulate abscisic acid-dependent stomatal closure
(American Society of Plant Biologist, 2014-12)
Abscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide (H2S), a small signaling gas molecule involved in key physiological processes in mammals, has been recently reported as a new component ...
The nitric oxide-sensitive p21Ras-ERK pathway mediates S-nitrosoglutathione-induced apoptosis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
p21Ras protein plays a critical role in cellular signaling that induces either cell cycle progression or apoptosis. Nitric oxide (NO) has been consistently reported to activate p21Ras through the redox sensitive cysteine ...
β-carbonic anhydrases play a role in salicylic acid perception in Arabidopsis
(Public Library of Science, 2017-07)
The plant hormone salicylic acid (SA) is required for defense responses. NON EXPRES-SER OF PATHOGENESIS RELATED 1 (NPR1) and NON RECOGNITION OF BTH-4 (NRB4) are required for the response to SA in Arabidopsis (Arabidopsis ...
ADPglucose pyrophosphorylase's N-terminus: Structural role in allosteric regulation
(Academic Press Inc Elsevier Science, 2006-04)
We studied the functional role of the Escherichia coli ADPglucose pyrophosphorylase's N-terminus in allosteric regulation, and the particular effects caused by its length. Small truncated mutants were designed, and those ...
Phytochrome control of the Arabidopsis transcriptome anticipates seedling exposure to light
(American Society of Plant Biologist, 2005-12)
Phytochromes mediate a profound developmental shift when dark-grown seedlings are exposed to light. Here, we show that a subset of genes is upregulated in phytochrome B (phyB) mutants even before dark-grown Arabidopsis ...
Understanding the allosteric trigger for the fructose-1,6-bisphosphate regulation of the ADP-glucose pyrophosphorylase from Escherichia coli
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-10)
ADP-glucose pyrophosphorylase is the enzyme responsible for the regulation of glycogen synthesis in bacteria. The enzyme N-terminal domain has a Rossmann-like fold with three neighbor loops facing the substrate ATP. In the ...
The nitric oxide-sensitive p21Ras-ERK pathway mediates S-nitrosoglutathione-induced apoptosis
(Elsevier B.V., 2008-05-16)
p21Ras protein plays a critical role in cellular signaling that induces either cell cycle progression or apoptosis. Nitric oxide (NO) has been consistently reported to activate p21Ras through the redox sensitive cysteine ...
