Ribose 5-phosphateAlpha-D-ribose 1-methylphosphonate 5-triphosphate synthase: Alpha-D-ribose 1-methylphosphonate 5-triphosphate synthase () is an enzyme with system name ATP:methylphosphonate 5-triphosphoribosyltransferase. This enzyme catalyses the following chemical reactionApioseCyclic ADP-riboseRibose-phosphate diphosphokinase: Ribose-phosphate diphosphokinase (or phosphoribosyl pyrophosphate synthetase or ribose-phosphate pyrophosphokinase) is an enzyme that converts ribose 5-phosphate into phosphoribosyl pyrophosphate (PRPP). It is classified under .Pentose phosphate pathwayTransketolase: Transketolase is an enzyme of both the pentose phosphate pathway in all organisms and the Calvin cycle of photosynthesis. It catalyzes two important reactions, which operate in opposite directions in these two pathways.Archaeosine synthase: Archaeosine synthase (, ArcS, TgtA2, MJ1022 (gene), glutamine:preQ0-tRNA amidinotransferase) is an enzyme with system name L-glutamine:7-cyano-7-carbaguanine aminotransferase. This enzyme catalyses the following chemical reactionDavidaster rubiginosusDeoxyriboseMonosaccharideNucleoside analogue: Nucleoside analogues are nucleosides which contain a nucleic acid analogue and a sugar. Nucleotide analogs are nucleotides which contain a nucleic acid analogue, a sugar and one to three phosphate groups.NTP binding site: An NTP binding site is a type of binding site found in nucleoside monophosphate (NMP) kinases, N can be adenosine or guanosine. A P-loop is one of the structural motifs common for nucleoside triphosphate (NTP) binding sites, it interacts with the bound nucleotide's phosphoryl groups.Coles PhillipsPurine nucleoside phosphorylase deficiencyBurst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".Clavibacter michiganensis: Clavibacter michiganensis is an aerobic non-sporulating Gram-positive plant pathogenic actinomycete that currently constitutes the only species within the genus Clavibacter. The other former Clavibacter species have been reclassified to genera Leifsonia, Rathayibacter and Curtobacterium.Reaction coordinateMizoribineNucleic acid structure: Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar.Adenosine receptor: The adenosine receptors (or P1 receptors) are a class of purinergic G protein-coupled receptors with adenosine as endogenous ligand.Spin–lattice relaxation in the rotating frame: Spin–lattice relaxation in the rotating frame is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value of zero, under the influence of a radio frequency (RF) field in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–lattice relaxation time constant in the rotating frame, T1ρ.List of strains of Escherichia coli: Escherichia coli is a well studied bacterium that was first identified by Theodor Escherich, after whom it was later named.PurineDNA binding site: DNA binding sites are a type of binding site found in DNA where other molecules may bind. DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.
