Synthesis of ultra-small cysteine-capped gold nanoparticles by pH switching of the Au(I)-cysteine polymer
(Elsevier, 2015-03)
We report a synthetic approach for the production of ultra-small (0.6 nm) gold nanoparticles soluble in water with a precise control of the nanoparticle size. Our synthetic approach utilizes a pH-depending Au/cysteine ...
Topology Dictates Evolution of Regulatory Cysteines in a Family of Viral Oncoproteins
(Oxford University Press, 2019-07)
Redox regulation in biology is largely operated by cysteine chemistry in response to a variety of cell environmental and intracellular stimuli. The high chemical reactivity of cysteines determines their conservation in ...
Negative modulation of the GABAAρ1 receptor function by l-cysteine
(Wiley Blackwell Publishing, Inc, 2018-01)
l-Cysteine is an endogenous sulfur-containing amino acid with multiple and varied roles in the central nervous system, including neuroprotection and the maintenance of the redox balance. However, it was also suggested as ...
Interaction of cysteine and its derivatives with monolayers of dipalmitoylphosphatidylcholine
(Elsevier B.V., 2019-12)
Molecular interactions between l-cysteine (Cys) and its ester derivatives (Cysx); l-cysteine ethyl ester (CE), l-cysteine methyl ester (CM) and N-acetyl l-cysteine (NAC) with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine ...
Characterization of Trypanosoma cruzi l-cysteine transport mechanisms and their adaptive regulation
(Wiley Blackwell Publishing, Inc, 2009-03)
L-Cysteine and methionine are unique amino acids that act as sulfur donors in all organisms. In the specific case of Trypanosomatids, L-cysteine is particularly relevant as a substrate in the synthesis of trypanothione. ...
Isolation and characterization of a cysteine proteinase from Fasciola hepatica adult worms
(Elsevier, 1989)
Adult Fasciola hepatica worms contain multiple proteinases capable of degrading hemoglobin, immunoglobulins and collagen. Here we report the isolation and biochemical characterization of a cysteine proteinase from acidic ...
De novo assembly of Vriesea carinata leaf transcriptome to identify candidate cysteine-proteases
(Elsevier, 2019)
Vriesea carinata is an endemic bromeliad from the Brazilian Atlantic Forest. It has trichome and tank system in their leaves which allows to absorb water and nutrients. It belongs to Bromeliaceae family, which includes ...
Antibacterial activity of a combination of cysteine and ciprofloxacin and its relationship with the generation of oxidative stress in extended-spectrum betalactamase-producing escherichia coli strains
(Life Science Informatics Publications, 2018-08)
The aim of the present work was to evaluate whether L-cysteine enhances theantibiotic susceptibility of extended-spectrum beta-lactamase (ESBL) Escherichia coli strains to ciprofloxacin and to identify the role of Reactive ...
Kinetic characterization of a novel cysteine peptidase from the protozoan Babesia bovis, a potential target for drug design
(Elsevier, 2020-12)
C1A cysteine peptidases have been shown to play an important role during apicomplexan invasion and egress of host red blood cells (RBCs) and therefore have been exploited as targets for drug development, in which peptidase ...
