CP12 residues involved in the formation and regulation of the glyceraldehyde-3-phosphate dehydrogenase-CP12-phosphoribulokinase complex in Chlamydomonas reinhardtii.

Mol. Biosyst. 8(11) , 2994-3002, (2012)

CP12, a member of the intrinsically disordered protein family, forms a stable complex with glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK). To understand the function of conserved residues of CP12 in the formation of the GAPDH-C...

Physicochemical changes in phosphorylase kinase induced by its cationic activator Mg(2+).

Protein Sci. 22(4) , 444-54, (2013)

For over four decades free Mg(2+) ions, that is, those in excess of MgATP, have been reported to affect a wide variety of properties of phosphorylase kinase (PhK), including its affinity for other molecules, proteolysis, chemical crosslinking, phosphorylation...

Glutathionylation in the photosynthetic model organism Chlamydomonas reinhardtii: a proteomic survey.

Mol. Cell. Proteomics 11(2) , M111.014142, (2012)

Protein glutathionylation is a redox post-translational modification occurring under oxidative stress conditions and playing a major role in cell regulation and signaling. This modification has been mainly studied in nonphotosynthetic organisms, whereas much ...

Kinetics, in silico docking, molecular dynamics, and MM-GBSA binding studies on prototype indirubins, KT5720, and staurosporine as phosphorylase kinase ATP-binding site inhibitors: the role of water molecules examined.

Proteins 79(3) , 703-19, (2011)

With an aim toward glycogenolysis control in Type 2 diabetes, we have investigated via kinetic experiments and computation the potential of indirubin (IC₅₀ > 50 μM), indirubin-3'-oxime (IC₅₀ = 144 nM), KT5720 (K(i) = 18.4 nM) and staurosporine (K(i) = 0.37 nM...

Flywheel resistance exercise to maintain muscle oxidative potential during unloading.

Aviat. Space. Environ. Med. 85(7) , 694-9, (2014)

As spaceflight compromises skeletal muscle oxidative and aerobic work capacity, this study assessed the efficacy of resistance exercise (RE) to counteract muscle metabolic perturbations induced by 5 wk unilateral lower limb unloading (UL).There were 21 men an...

Daphnetin methylation stabilizes the activity of phosphoribulokinase in wheat during cold acclimation.

Biochem. Cell Biol. 90(5) , 657-66, (2012)

The methylation of daphnetin (7,8-dihydroxycoumarin) to its 8-methyl derivative is catalyzed by a wheat (Triticum aestivum L.) O-methyltransferase (TaOMT1). This enzyme is regulated by cold and photosystem II excitation pressure (plastid redox state). Here, w...

20-HETE induces hyperglycemia through the cAMP/PKA-PhK-GP pathway.

Mol. Endocrinol. 26(11) , 1907-16, (2012)

We previously generated cytochrome P450 4F2 (CYP4F2) transgenic mice and showed high 20-hydroxyeicosatetraenoic acid (20-HETE) production, which resulted in an elevation of blood pressure. However, it was unclear whether 20-HETE affected glucose metabolism. W...

Conformational modulation and hydrodynamic radii of CP12 protein and its complexes probed by fluorescence correlation spectroscopy.

FEBS J. 281(14) , 3206-17, (2014)

Light/dark regulation of the Calvin cycle in oxygenic photosynthetic organisms involves the formation and dissociation of supramolecular complexes between CP12, a nuclear-encoded chloroplast protein, and the two enzymes glyceraldehyde-3-phosphate dehydrogenas...

A novel PHKA2 gross deletion mutation in a Korean patient with X-linked liver glycogenosis type I.

Ann. Clin. Lab. Sci. 41(2) , 197-200, (2011)

X-linked liver glycogenosis (XLG) is caused by a mutation in the PHKA2 gene which encodes the alpha subunit of phosphorylase kinase (PHK). Although XLG is not a rare disease, there have been no reports of PHKA2 mutations in Koreans. A 5-year-old boy presented...

Inter-species variation in the oligomeric states of the higher plant Calvin cycle enzymes glyceraldehyde-3-phosphate dehydrogenase and phosphoribulokinase.

J. Exp. Bot. 62(11) , 3799-805, (2011)

In darkened leaves the Calvin cycle enzymes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK) form a regulatory multi-enzyme complex with the small chloroplast protein CP12. GAPDH also forms a high molecular weight regulatory mono...
