DNA sequence variation in the promoter region of the VEGF gene impacts VEGF gene expression and maximal oxygen consumption.
Authors:Prior SJ, Hagberg JM, Paton CM, Douglass LW, Brown MD, McLenithan JC, Roth SM,
Journal:Am J Physiol Heart Circ Physiol
PubMed ID:16339827
'In its role as an endothelial cell proliferation and migration factor, vascular endothelial growth factor (VEGF) can affect peripheral circulation, and therefore impact maximal oxygen consumption (Vo2max). Because of the role of VEGF, and because variation in the VEGF gene has the ability to alter VEGF gene expression and VEGF ... More
Identification of coenzyme M biosynthetic phosphosulfolactate synthase: a new family of sulfonate-biosynthesizing enzymes.
Authors: Graham David E; Xu Huimin; White Robert H;
Journal:J Biol Chem
PubMed ID:11830598
'The hyperthermophilic euryarchaeon Methanococcus jannaschii uses coenzyme M (2-mercaptoethanesulfonic acid) as the terminal methyl carrier in methanogenesis. We describe an enzyme from that organism, (2R)-phospho-3-sulfolactate synthase (ComA), that catalyzes the first step in coenzyme M biosynthesis. ComA catalyzed the stereospecific Michael addition of sulfite to phosphoenolpyruvate over a broad range ... More
Biosynthesis of riboflavin in archaea studies on the mechanism of 3,4-dihydroxy-2-butanone-4-phosphate synthase of Methanococcus jannaschii.
Authors:Fischer M, Romisch W, Schiffmann S, Kelly M, Oschkinat H, Steinbacher S, Huber R, Eisenreich W, Richter G, Bacher A,
Journal:J Biol Chem
PubMed ID:12200440
'The hypothetical protein predicted by the open reading frame MJ0055 of Methanococcus jannaschii was expressed in a recombinant Escherichia coli strain under the control of a synthetic gene optimized for translation in an eubacterial host. The recombinant protein catalyzes the formation of the riboflavin precursor 3,4-dihydroxy-2-butanone 4-phosphate from ribulose 5-phosphate ... More
Characterization of the SECIS binding protein 2 complex required for the co-translational insertion of selenocysteine in mammals.
Authors:Kinzy SA, Caban K, Copeland PR,
Journal:Nucleic Acids Res
PubMed ID:16155186
'Selenocysteine is incorporated into at least 25 human proteins by a complex mechanism that is a unique modification of canonical translation elongation. Selenocysteine incorporation requires the concerted action of a kink-turn structural RNA (SECIS) element in the 3'' untranslated region of each selenoprotein mRNA, a selenocysteine-specific translation elongation factor (eEFSec) ...

Substantially enhanced cloning efficiency of SAGE (Serial Analysis of Gene Expression) byadding a heating step to the original protocol.
Authors:Kenzelmann M, Muhlemann K
Journal:Nucleic Acids Res
PubMed ID:9889294
'The efficiency of the original SAGE (Serial Analysis of Gene Expression) protocol was limited by a small average size of cloned concatemers. We describe a modification of the technique that overcomes this problem. Ligation of ditags yields concatemers of various sizes. Small concatemers may aggregate and migrate with large ones ... More
