Transcription of TP0126, Treponema pallidum putative OmpW homolog, is regulated by the length of a homopolymeric guanosine repeat
(American Society for Microbiology, 2015)
An effective mechanism for introduction of phenotypic diversity within a bacterial population exploits changes in the length of repetitive DNA elements located within gene promoters. This phenomenon, known as phase variation, ...
Synthesis and characterization of Sb(V)-adenosine and Sb(V)-guanosine complexes in aqueous solution
(Elsevier Science SaLausanneSuíça, 2006)
Inhibition of Tubulin Self-Assembly and Tubulin-Colchicine GTPase Activity by Guanosine 5’-γ-Fluorotriphosphate)
(1987)
The inhibitory effects of guanosine 5'-(ᵧ-fluorotriphosphate) [GTP(ᵧF)] on both the polymerization and the colchicine-dependent GTPase activity of calf brain tubulin have been studied. The results demonstrate that this ...
The Syn-Anti Equilibrium of Guanosine Cyclic 3',5'- Monophosphate and 8-Sustituted Derivatives: A Theoretical Study
(Sociedad Chilena de Química, 2000)
Electrophysiological effects of guanosine and MK-801 in a quinolinic acid-induced seizure model
(2010)
Quinolinic acid (QA) is an N-methyl-D-aspartate receptor agonist that also promotes glutamate release and
inhibits glutamate uptake by astrocytes. QA is used in experimental models of seizures studying the effects ...
UMP kinase from Mycobacterium tuberculosis: Mode of action and allosteric interactions, and their likely role in pyrimidine metabolism regulation
(2011-01-15)
The pyrH-encoded uridine 5′-monophosphate kinase (UMPK) is involved in both de novo and salvage synthesis of DNA and RNA precursors. Here we describe Mycobacterium tuberculosis UMPK (MtUMPK) cloning and expression in ...
Changes in purines concentration in the cerebrospinal fluid of patients experiencing pain: A case-control study
(ELSEVIER IRELAND LTD, 2010)
This study analyzes the relationship between extracellular purines and pain perception in humans. Cerebrospinal fluid (CSF) levels of purines and their metabolites were compared between patients displaying acute and/or ...
