  1. Nucleotide exchange factor

    Unreferenced date December 2009 Nucleotide exchange factor s NEF s are protein s that stimulate the exchange replacement of nucleoside diphosphate s for nucleoside triphosphate s bound to other proteins. Function Many cellular proteins cleave hydrolysis hydrolyze nucleoside triphosphates&ndash adenosine triphosphate ATP or guanosine triphosphate GTP &ndash to their diphosphate forms adenosine diphosphate ADP and guanosine diphosphate GDP as a source of energy and to drive conformational changes. These changes in turn affect the structural, enzyme enzymatic , or signalling properties of the protein. Nucleotide exchange factors actively assist in the exchange of depleted nucleoside diphosphates for fresh nucleoside triphosphates. NEFs are specific for the nucleotides they exchange ADP or GDP, but not both and are often specific to a single protein or class of proteins with which they interact.

  1. Guanylyl transferase

    Guanylyl transferases are enzyme s that transfer a guanosine monophosphate GMP also known as guanylic acid group, usually from Guanosine triphosphate GTP to another molecule, releasing pyrophosphate . Many eukaryote eukaryotic guanylyl transferases are capping enzyme s that catalyze the formation of the 5 cap in the co transcriptional modification of messenger RNA . Because the 5 end of the RNA molecule ends in a phosphate group, the bond formed between the RNA and the GTP molecule is an unusual 5 5 triphosphate linkage, instead of the 3 5 linkages between the other nucleotides that form an RNA strand. In capping enzymes, a highly conserved lysine residue serves as the catalytic residue that forms a covalent enzyme GMP complex. ref name Fresco Fresco LD, Buratowski S. 1994 .

  1. Purine nucleotide cycle

    The Purine Nucleotide Cycle is a metabolic pathway in which fumarate is generated from aspartate in order to increase the concentration of Krebs cycle intermediates. ref Salway, J. G., Metabolism at a glance 3rd edition , Blackwell Publishing Ltd., Oxford, 2004, pp. 56 57 ref The pathway was first described by John Lowenstein, who demonstrated its role in increasing the rate of oxidative phosphorylation in skeletal muscle . ref Voet, D., Voet, J. G., Biochemistry 3rd Edition , John Wiley & Sons, Inc., 2004, pp. 1094 1095 ref Outline The cycle is composed of three Enzyme enzyme catalysed reactions. The first stage is the deamination of the purine nucleotide Adenosine monophosphate AMP to form inosine monophosphate IMP , catalysed by the enzyme AMP deaminase AMP H sub 2 sub O IMP NH sub 4 sub sup sup The second stage is the formation of adenylosuccinate from IMP and the amino acid aspartate , which is coupled to the energetically favourable hydrolysis of Guanosine triphosphate GTP , and catalysed by the enzyme adenylosuccinate synthetase Aspartate IMP GTP Adenylosuccinate Guanosine diphosphate GDP Inorganic phosphate P sub i sub Finally, Adenylosuccinate is cleaved by the enzyme adenylosuccinate lyase to release fumarate and regenerate the starting material of AMP Adenylosuccinate AMP Fumarate References ISBN Reflist Category Purines Category Metabolic pathways Category Biochemistry fr Cycle des nucl otides puriques zh ...   more details
