1. Identificação de fatores de transcrição e sinais celulares que regulam a expressão do gene cspC em Caulobacter crescentus. / Identification of transcription factors and cellular signals that regulate cspC gene expression from Caulobacter crescentus.
As proteínas de choque frio pertencem a uma família de proteínas com um domínio altamente conservado, denominado domínio de choque frio (CSD). Estão envolvidas em vários processos celulares, incluindo adaptação a baixas temperaturas, estresse nutricional e fase estacionária. Em C. crescentus, uma α-proteobacteria não pat

2. Estudo da regulação do gene cspD de Caulobacter crescentus. / The study of cspD gene regulation in Caulobacter crescentus.
CspD é uma das quatro proteínas de choque frio de Caulobacter crescentus, sendo maior que as outras CSPs por possuir dois domínios de choque frio, e tem seu papel na célula ainda desconhecido. O objetivo deste trabalho foi identificar e caracterizar os fatores in cis e in trans envolvidos na regulação da expressão do gene cspD em C. crescentus. Neste

3. Estudo de genes de Caulobacter crescentus importantes para a sobrevivência em baixas temperaturas. / Study of Caulobacter crescentus genes important to low temperature survival.
Caulobacter crescentus sobrevive em baixas temperaturas e mostrou ser um organismo psicrotolerante e de alta resistência ao congelamento, característica resultante de múltiplos fatores. C. crescentus possui quatro genes codificantes para CSPs, sendo cspA e cspB induzidos em baixas temperaturas e cspB, cspC e cspD em fase estacionária. A ausência de cspA

4. Análise do papel do gene cspC de Caulobacter crescentus e de sua regulação. / Study of the role cspC gene from Caulobacter crescentus and its regulation.
The cold shock response in bacteria involves the expression of cold shock proteins (CSPs), which destabilize secondary structures on mRNAs, allowing their translation. Caulobacter crescentus possesses four genes encoding CSPs: cspA and cspB are induced upon cold shock, while cspC and cspD are induced at stationary phase. In this work, a new sequence for the

5. Variabilidade genética entre isolados do Coconut lethal yellowing phytoplasmas determinada pela mobilidade eletroforética dos ADNs heteroduplexes
A mobilidade eletroforética dos ADNs heteroduplexes foi usada para determinar a diversidade genômica entre isolados africanos dos fitoplasmas do amarelecimento letal dos coqueiros que causam as doenças denominadas, Cape St. Paul wilt disease (CSPD, Gana), lethal disease (LD, Tanzânia) e o lethal yellowing (LYM, Moçambique). Eles foram também comparados

6. Growth-phase-dependent expression of cspD, encoding a member of the CspA family in Escherichia coli.
The cspD gene of Escherichia coli encodes a protein of high sequence similarity with the cold shock protein CspA, but cspD expression is not induced by cold shock. In this study, we analyzed the regulation of cspD gene expression. By using a cspD-lacZ fusion and primer extension analysis, the expression of cspD was found to be dramatically induced by station

7. Identification and Transcriptional Control of Caulobacter crescentus Genes Encoding Proteins Containing a Cold Shock Domain
The cold shock proteins are small peptides that share a conserved domain, called the cold shock domain (CSD), that is important for nucleic acid binding. The Caulobacter crescentus genome has four csp genes that encode proteins containing CSDs. Three of these (cspA, cspB, and cspC) encode peptides of about 7 kDa and are very similar to the cold shock protein

8. Localization of Cold Shock Proteins to Cytosolic Spaces Surrounding Nucleoids in Bacillus subtilis Depends on Active Transcription
Using immunofluorescence microscopy and a fusion of a cold shock protein (CSP), CspB, to green fluorescent protein (GFP), we showed that in growing cells Bacillus subtilis CSPs specifically localize to cytosolic regions surrounding the nucleoid. The subcellular localization of CSPs is influenced by the structure of the nucleoid. Decondensed chromosomes in sm

9. CspI, the Ninth Member of the CspA Family of Escherichia coli, Is Induced upon Cold Shock
Escherichia coli contains the CspA family, consisting of nine proteins (CspA to CspI), in which CspA, CspB, and CspG have been shown to be cold shock inducible and CspD has been shown to be stationary-phase inducible. The cspI gene is located at 35.2 min on the E. coli chromosome map, and CspI shows 70, 70, and 79% identity to CspA, CspB, and CspG, respectiv

10. Cold Shock Proteins of Lactococcus lactis MG1363 Are Involved in Cryoprotection and in the Production of Cold-Induced Proteins
Members of the group of 7-kDa cold-shock proteins (CSPs) are the proteins with the highest level of induction upon cold shock in the lactic acid bacterium Lactococcus lactis MG1363. By using double-crossover recombination, two L. lactis strains were generated in which genes encoding CSPs are disrupted: L. lactis NZ9000ΔAB lacks the tandemly orientated cspA

11. Physiological and Regulatory Effects of Controlled Overproduction of Five Cold Shock Proteins of Lactococcus lactis MG1363
The physiological and regulatory effects of overproduction of five cold shock proteins (CSPs) of Lactococcus lactis were studied. CspB, CspD, and CspE could be overproduced at high levels (up to 19% of the total protein), whereas for CspA and CspC limited overproduction (0.3 to 0.5% of the total protein) was obtained. Northern blot analysis revealed low abun
