Mapping eIF5A binding sites for Dys1 and Lia1: In vivo evidence for regulation of eIF5A hypusination
(2003-12-18)
The evolutionarily conserved factor eIF5A is the only protein known to undergo hypusination, a unique posttranslational modification triggered by deoxyhypusine synthase (Dys1). Although eIF5A is essential for cell viability, ...
ZmPUMP encodes a fully functional monocot plant uncoupling mitochondrial protein whose affinity to fatty acid is increased with the introduction of a His pair at the second matrix loop
(2006-05-26)
Uncoupling proteins (UCPs) are specialized mitochondrial transporter proteins that uncouple respiration from ATP synthesis. In this study, cDNA encoding maize uncoupling protein (ZmPUMP) was expressed in Escherichia coli ...
Synergy of DNA-bending nucleoid proteins and macromolecular crowding in condensing DNA
(2007-10-01)
Many prokaryotic nucleoid proteins bend DNA and form extended helical protein-DNA fibers rather than condensed structures. On the other hand, it is known that such proteins (such as bacterial HU) strongly promote DNA ...
Oxidation and nitration of ribonuclease and lysozyme by peroxynitrite and myeloperoxidase
(ELSEVIER SCIENCE INC, 2009)
In spite of the many studies on protein modifications by reactive species, knowledge about the products resulting from the oxidation of protein-aromatic residues, including protein-derived radicals and their stable products, ...
Immunohistochemical expression of PCNA, p53, bax and bcl-2 in oral lichen planus and epithelial dysplasia.
(2009-03-01)
The potential for malignant transformation of oral lichen planus is still controversial. The expression of proteins related to cell proliferation and apoptosis in oral lichen planus and epithelial dysplasia was analyzed ...
Apoptose em otorrinolaringologia e cabeça e pescoço
(2003-06-01)
This paper intend to review recent advances in our understanding of programmed cell death, or apoptosis, and discuss implications of these basic science advances in the development of causes and potential treatments of a ...
Protein–protein interaction map of the Trypanosoma cruzi ribosomal P protein complex
(Elsevier Science, 2005-09)
The large subunit of the eukaryotic ribosome possesses a long and protruding stalk formed by the ribosomal P proteins. Four out of five ribosomal P proteins of Trypanosoma cruzi, TcP0, TcP1alpha, TcP2alpha, and TcP2beta ...
Electrostatic interaction between proteins and polysaccharides: Physicochemical aspects and applications in emulsion stabilization
(2019-01-02)
Colloidal particle systems based on natural biopolymers are widely used in food industries and their production can involve an emulsification step during processing, which is induced by interaction of a primary emulsion, ...
