AMP hydrolysis in soluble and microsomal rat cardiac cell fractions: kinetic characterization and molecular identification of 5 `-nucleotidase
(PORTLAND PRESS LTD, 2008)
The present study describes the enzymatic properties and molecular identification of 5`-nucleotidase in soluble and microsomal fractions from rat cardiac ventricles. Using AMP as a substrate, the results showed that the ...
In vivo studies of cyclic AMP phosphodiesterase activity in microinjected amphibian oocytes
(1976)
Using the microinjection technique it has been possible to measure the hydrolysis of (H3) cAMP injected into Xenopus laevis oocytes. A very active cAMP phosphosidiesterase activity hydrolyzes its substrate to 5'AMP at a ...
Hidrolise de nucleotideos da adenina em pacientes com meningite asseptica e bacteriana
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2007-11-30)
The meningitis is a serious inflammatory illness of meninges, the membranes that recover and protect encephalo and the spinal cord. The main causing agents of the meningitis are the viruses and the bacteria. Some works ...
Biochemical and Molecular Characterization of Three New Variants of AmpC β-Lactamases from Morganella morganii
(American Society for Microbiology, 2006-03)
Morganella morganii produces an inducible, chromosomally encoded AmpC beta-lactamase. We describe in this study three new variants of AmpC within this species with apparent pIs of 6.6 (M19 from M. morganii strain PP19), ...
Diminution in adenine nucleotide hydrolysis by platelets and serum from rats submitted to Walker 256 tumour
(SpringerDordrechtHolanda, 2006)
Enzimas que hidrolisam nucleotídeos da adenina em plaquetas de pacientes com câncer de mama
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2004-04-26)
The activities of the enzymes NTPDase (E.C. 3.6.1.5, apyrase,
ecto/CD39) and 5'-nucleotidase (E.C. 3.1.3.5, CD73) were analyzed in platelets
from breast cancer patients. Initially, patients were compared in terms of ...
Comparison of in vivo and in vitro properties of cyclic adenosine 3':5' monophosphate phosphodiesterase of amphibian oocytes
(1977)
The cAMP levels of single Xenopus laevis oocytes are shown to range from 1 to 4 μM and those of isolated nuclei to be about 7 to 10 μM. The oocyte is capable of hydrolyzing a large molar excess of microinjected cAMP, rapidly ...
Thyroid hormones alter the adenine nucleotide hydrolysis in adult rat blood serum
(WILEY-BLACKWELL, 2011)
The effects of ATP, ADP, and adenosine in the processes of platelet aggregation, vasodilatation, and coronary flow have been known for many years. The sequential hydrolysis of ATP to adenosine by soluble nucleotidases ...
Development of a novel catalytic amyloid displaying a metal-dependent ATPase-like activity
(Elsevier B.V., 2017)
Amyloids are protein aggregates of highly regular structure that are involved in diverse pathologies such as Alzheimer's and Parkinson's disease. Recent evidence has shown that under certain conditions, small peptides can ...
