Possible thiol group involvement in intracellular pH effect on low- conductance Ca2+-dependent K+ channels
(1997)
We have studied the effect of intracellular pH (pH(i)) shifts on the activity of Ca2+-dependent, inwardly rectifying K+ channels of HeLa cells. Recordings of macroscopic currents in symmetrical 145 mM K+ and internal pH ...
An amperometric sensor for L-cysteine based on nanostructured platform modified with 5,5 '-dithiobis-2-nitrobenzoic acid (DTNB)
(Elsevier Science SaLausanneSuíça, 2010)
Ca2+-activated K+ channel inhibition by reactive oxygen species
(AMER PHYSIOLOGICAL SOC, 2002-03)
We studied the effect of H2O2 on the gating behavior of large-conductance Ca2+-sensitive voltage-dependent K+ (K-V,K-Ca) channels. We recorded potassium currents from single skeletal muscle channels incorporated into ...
Kinetic studies of rat liver hexokinase D ('glucokinase') in non-co-operative conditions show an ordered mechanism with MgADP as the last product to be released
(2003)
The kinetic mechanism of rat liver hexokinase D (‘ glucokinase’)
was studied under non-co-operative conditions with 2-
deoxyglucose as substrate, chosen to avoid uncertainties derived
from the co-operativity observed ...
Chemical modification of SH groups of E. coli Phosphofructokinase-2 induces subunit dissociation: Monomers are inactive but preserve ligand binding properties
(Taylor & Francis, 2000)
Modification of Escherichia coli phosphofructokinase-2 (Pfk-2) with N- (1-pyrenil)maleimide results in an enzyme form that is inactive. However, the rate of modification is drastically reduced in the presence of the ...
Salmonella Typhimurium exhibits fluoroquinolone resistance mediated by the accumulation of the antioxidant molecule H2S in a CysK-dependent manner
(2016)
Objectives: To evaluate the contribution of cysK and cysM to the fluoroquinolone (ofloxacin) antibiotic resistance in Salmonella Typhimurium, and their impact on H2S and cysteine production through targeted mutagenesis. ...
ENDO-OLIGOPEPTIDASE-A, A PUTATIVE ENKEPHALIN-GENERATING ENZYME, in the VERTEBRATE RETINA
(Lippincott-raven Publ, 1991-11-01)
Endo-oligopeptidase A, EC 3.4.22.19, converts small enkephalin-containing peptides into the corresponding enkephalins in vitro. We investigated the presence of endooligopeptidase A in the retina and its possible colocalization ...

Avaliação in vitro do óleo da semente de chia (Salvia hispânica L.) na atividade de enzimas antioxidantes em ratos
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de AlimentosTecnologia em AlimentosUTFPR, 2017-11-28)
Cholinergic neurons are related to important neurological functions that are impaired in cases of deficiency in the secretion of the neurotransmitter acetylcholine (ACh), one of the first neurotransmitters discovered and ...
