CAP-MAP: cap analysis protocol with minimal analyte processing, a rapid and sensitive approach to analysing mRNA cap structures [PDF]
Eukaryotic messenger RNA (mRNA) is modified by the addition of an inverted guanosine cap to the 5′ triphosphate. The cap guanosine and initial transcribed nucleotides are further methylated by a series of cap methyltransferases to generate the mature cap

We report the results of computational studies of the guanosine triphosphate (GTP) hydrolysis in the active site of the KRas-NF1 protein complex, where KRas stands for the K-isoform of the Ras (ras sarcoma) protein and NF1 (neurofbromin-1) is the ...

The molecular genetics of RASopathies: An update on novel disease genes and new disorders
Abstract Enhanced signaling through RAS and the mitogen‐associated protein kinase (MAPK) cascade underlies the RASopathies, a family of clinically related disorders affecting development and growth. In RASopathies, increased RAS‐MAPK signaling can result from the upregulated activity of various RAS GTPases, enhanced function of proteins positively ...

Kinetics of Phosphate Incorporation into Adenosine Triphosphate and Guanosine Triphosphate in Bacteria [PDF]
Escherichia coli cells were labeled with 33 PO 4 for several generations and then 32 PO 4 was added, samples were taken at various times, and adenosine triphosphate (ATP) and guanosine triphosphate (GTP) were purified from an acid ...

Regulation of the Single Polar Flagellar Biogenesis
Some bacterial species, such as the marine bacterium Vibrio alginolyticus, have a single polar flagellum that allows it to swim in liquid environments.

Advanced Raman spectroscopy detection of oxidative damage in nucleic acid bases: probing chemical changes and intermolecular interactions in guanosine at ultralow concentration [PDF]
DNA/RNA synthesis precursors are especially vulnerable to damage induced by reactive oxygen species occurring following oxidative stress. Guanosine triphosphates are the prevalent oxidized nucleosites, which can be misincorporated during replication, leading to mutations and cell death. Here, we present a novel method based on micro-Raman spectroscopy,

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Guanosine triphosphate cyclohydrolase activity in rat tissues [PDF]
The GTP cyclohydrolase activity of rat tissues has been studied by means of the measurement of formic acid release and neopterin synthesis from GTP. After gel filtration of a 45%-satd.-(NH4)2SO4 fraction of liver homogenates, three enzyme fractions were separated and named A1, A2 and A3 according to the order of their elution.
