1. Expressão diferencial dos genes VuUCP1a e VuUCP1b em caupi sob estresse salino
O estresse salino afeta o crescimento e o desenvolvimento das plantas, induzindo respostas bioquímicas e fisiológicas como mecanismo de adaptação para sua sobrevivência. As proteínas desacopladoras de planta (pUCPs) dissipam o gradiente eletroquímico mitocondrial de prótons como calor e são codificadas por famílias multigênicas. Elas atuam como si

2. CaracterizaÃÃo da ProteÃna desacopladora mitocondrial (pUCP) de Vigna unguiculata (L.) Walp / CHARACTERIZATION OF PLANT UNCOUPLING PROTEIN(pUCP) OF Vigna unguiculata (L.) WALP
As proteÃnas desacopladoras de planta (pUCPs) sÃo proteÃnas integrais de membrana, localizadas na membrana mitocondrial interna, pertencentes a FamÃlia de Carreadores de Ãnions Mitocondriais (FCAM), responsÃveis pela dissipaÃÃo do gradiente eletroquÃmico de prÃtons, gerado pela respiraÃÃo, como calor. Na presenÃa de Ãcidos graxos livres (AGL),

3. Acquisition of Expression of the Pseudomonas aeruginosa ExoU Cytotoxin Leads to Increased Bacterial Virulence in a Murine Model of Acute Pneumonia and Systemic Spread
Pseudomonas aeruginosa is the nosocomial bacterial pathogen most commonly isolated from the respiratory tract. Animal models of this infection are extremely valuable for studies of virulence and immunity. We thus evaluated the utility of a simple model of acute pneumonia for analyzing P. aeruginosa virulence by characterizing the course of bacterial infectio

4. Analysis of the puc Operon Promoter from Rhodobacter capsulatus
Expression of the Rhodobacter capsulatus puc operon, which codes for structural polypeptides of the light-harvesting-II peripheral antenna complex, is highly regulated in response to alterations in oxygen tension and light intensity. To obtain an understanding of the puc promoter region we report the high-resolution 5′ mapping of the puc mRNA transcription

5. Susceptibility to beta-lactam antibiotics of Pseudomonas aeruginosa overproducing penicillin-binding protein 3.
By using a broad-host-range vector, pUCP27, the Pseudomonas aeruginosa and Escherichia coli pbpB genes, which encode penicillin-binding protein 3 (PBP3), were separately overexpressed in a P. aeruginosa strain, PAO4089, that is deficient in producing chromosomal beta-lactamase. Susceptibility studies indicated that overproduction of the P. aeruginosa PBP3 in

6. Genetic definition of the substrate selectivity of outer membrane porin protein OprD of Pseudomonas aeruginosa.
Earlier studies proved that Pseudomonas aeruginosa OprD is a specific porin for basic amino acids and imipenem. It was also considered to function as a nonspecific porin that allowed the size-dependent uptake of monosaccharides and facilitation of the uptake of quinolone and other antibiotics. In the present study, we utilized P. aeruginosa strains with gene

7. Identification of a penicillin-binding protein 3 homolog, PBP3x, in Pseudomonas aeruginosa: gene cloning and growth phase-dependent expression.
A homolog of Pseudomonas aeruginosa penicillin-binding protein 3 (PBP3), named PBP3x in this study, was identified by using degenerate primers based on conserved amino acid motifs in the high-molecular-weight PBPs. Analysis of the translated sequence of the pbpC gene encoding this PBP3x revealed that 41 and 48% of its amino acids were identical to those of E
