glyceraldehyde 3 phosphate/arabidopsis thaliana

We report the characterization of cis-acting elements involved in light regulation of the nuclear gene (GapA) that encodes the A subunit of glyceraldehyde 3-phosphate dehydrogenase in Arabidopsis thaliana. Our previous deletion analyses indicate that the -277 to -195 upstream region of GapA is

Plants contain both cytosolic and chloroplastic GAPDHs (glyceraldehyde-3-phosphate dehydrogenases). In Arabidopsis thaliana, cytosolic GAPDH is involved in the glycolytic pathway and is represented by two differentially expressed isoforms (GapC1 and GapC2) that are 98% identical in amino acid

We have characterized cis-acting elements involved in light regulation of the nuclear gene (GapA) encoding the A subunit of chloroplast glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in Arabidopsis thaliana. Our results show that a 1.1-kb promoter fragment of the GapA gene is sufficient to confer

Both cDNA and genomic clones for the nuclear genes encoding chloroplast (cp) (gapA and gapB) and cytosolic (gapC) glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from Arabidopsis thaliana have been isolated and characterized. Genomic Southern-blot analyses indicate that there is only one copy of

The promoter of the nuclear gene, GAPB, which encodes the B subunit of chloroplast glyceraldehyde-3-phosphate dehydrogenase (GADPH) of Arabidopsis thaliana, was previously shown to contain four direct repeats (Gap boxes, located between -237 and -181) that were necessary but not sufficient for

The crystal structure of the A(4) isoform of photosynthetic glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from Arabidopsis thaliana, expressed in recombinant form and complexed with NAD, is reported. The crystals, which were grown in 2.4 M ammonium sulfate and 0.1 M sodium citrate, belonged to

The metabolic role and regulation of selenium, particularly in plants, is poorly understood. One of the proteins probably involved in the metabolic regulation of this element is the selenium-binding protein (SBP) with homologues present across prokaryotic and eukaryotic species. The high degree of

Non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase (np-Ga3PDHase) plays a key metabolic role in higher plants. Purification to homogeneity of enzymes found in relatively low abundance in plants represents a major technical challenge that can be solved by molecular gene cloning and

We have characterized the effects of different light spectra on expression of the nuclear genes (GapA and GapB) encoding chloroplast glyceraldehyde-3-phosphate dehydrogenase in Arabidopsis thaliana. Steady-state mRNA levels for both genes in etiolated seedlings increased after a short exposure to

OBJECTIVE Cysteines and H2O2 are fundamental players in redox signaling. Cysteine thiol deprotonation favors the reaction with H2O2 that generates sulfenic acids with dual electrophilic/nucleophilic nature. The protein microenvironment surrounding the target cysteine is believed to control whether

In a previous study of Arabidopsis thaliana (J. Dewdney, T.R. Conley, M.-C. Shih, H.M. Goodman [1993] Plant Physiol 103: 1115-1121), it was postulated that both blue light receptor- and phytochrome-mediated pathways contribute to regulation of the nuclear genes encoding A and B subunits of

We report here the identification of a cis-acting region involved in light regulation of the nuclear gene (GapB) encoding the B subunit of chloroplast glyceraldehyde 3-phosphate dehydrogenase from Arabidopsis thaliana. Our results show that a 664-bp GapB promoter fragment is sufficient to confer

The E3 ubiquitin-protein ligases are associated to various processes such as cell cycle control and diverse developmental pathways. Arabidopsis thaliana SEVEN IN ABSENTIA like 7, which has ubiquitin ligase activity, is located in the nucleus and cytosol and is expressed at several stages in almost

Non-phosphorylating glyceraldehyde- 3-phosphate dehydrogenase (NP-GAPDH) is a conserved cytosolic protein found in higher plants. In photosynthetic cells, the enzyme is involved in a shuttle transfer mechanism to export NADPH from the chloroplast to the cytosol. To investigate the role of this

Photosynthetic glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK) interact in the chloroplast stroma through the action of the small peptide CP12. This supramolecular complex concurs with the light-dependent modulation in vivo of GAPDH and PRK activities. The expression
