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. ...
Cysteine-rich positions outside the structural zinc motif of human papillomavirus E7 provide conformational modulation and suggest functional redox roles
(American Chemical Society, 2014-02)
The E7 protein from high-risk human papillomavirus is essential for cell transformation in cervical, oropharyngeal, and other HPV-related cancers, mainly through the inactivation of the retinoblastoma (Rb) tumor suppressor. ...
Sensor for cysteine based on oxovanadium(IV) complex of Salen modified carbon paste electrode
(Elsevier B.V., 2005-05-13)
The electrochemical behavior of a carbon paste electrode modified (CPEM) with N,N′-ethylenebis(salicylideneiminato)oxovanadium(IV) complex ([(VO)-O-IV(Salen)]) was investigated as a new sensor for cysteine. Cyclic ...
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 ...
Sensor for cysteine based on oxovanadium(IV) complex of Salen modified carbon paste electrode
(Elsevier B.V., 2005-05-13)
The electrochemical behavior of a carbon paste electrode modified (CPEM) with N,N′-ethylenebis(salicylideneiminato)oxovanadium(IV) complex ([(VO)-O-IV(Salen)]) was investigated as a new sensor for cysteine. Cyclic ...
Structural and functional studies of the Mitochondrial Cysteine Desulfurase from Arabidopsis thaliana
(Oxford University Press, 2012-09)
AtNfs1 is the Arabidopsis thaliana mitochondrial homolog of the bacterial cysteine desulfurases NifS and IscS, having an essential role in cellular Fe–S cluster assembly. Homology modeling of AtNfs1m predicts a high global ...
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 ...
Avaliação da adição de cisteína no sêmen resfriado para inseminação em suíno
(Universidade Federal de Santa MariaBRMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina Veterinária, 2009-08-07)
The improvement of pig industry is a consequence of the technological advances. The aim of the present
study is to evaluate the effect of cysteine in BTS (Beltsville Thawing Solution) and centrifugation on swine
semen ...
An unusual cysteine VL87 affects the antibody fragment conformations without interfering with the disulfide bond formation
(Pergamon-Elsevier Science Ltd, 2017-10)
The Cys residues are almost perfectly conserved in all antibodies. They contribute significantly to the antibody fragment stability. The relevance of two natural contiguous Cys residues of an anti-recombinant human-follicle ...
