1. Investigação da biossíntese de toxinas produzidas por cepas de cianobactérias / Investigation on the cyanobacterial strains toxins biossinthesys
A demanda crescente de água doce de boa qualidade são problemas atuais e mundiais, além do descaso com os dejetos lançados nos ambientes aquáticos que comprometem a qualidade dos recursos hídricos. Um dos parâmetros que atesta a potabilidade da água é a presença de cianobactérias e cianotoxinas. Cianobactérias são microrganismos procariontes aer

2. Inactivation of an ABC Transporter Gene, mcyH, Results in Loss of Microcystin Production in the Cyanobacterium Microcystis aeruginosa PCC 7806
The cyanobacterium Microcystis aeruginosa is widely known for its production of the potent hepatotoxin microcystin. Microcystin is synthesized nonribosomally by the thiotemplate function of a large, modular enzyme complex encoded within the 55-kb microcystin synthetase (mcy) gene cluster. Also encoded within the mcy gene cluster is a putative ATP binding cas

3. Gene cloning and expression and characterization of a toxin-sensitive protein phosphatase from the methanogenic archaeon Methanosarcina thermophila TM-1.
With oligonucleotides modelled after conserved regions within the protein-serine/threonine phosphatases (PPs) of the PP1/2A/2B superfamily, the gene for the archaeal protein phosphatase PP1-arch2 was identified, cloned, and sequenced from the methanogenic archaeon Methanosarcina thermophila TM-1. The DNA-derived amino acid sequence of PP1-arch2 exhibited a h

4. Inhibitors of Protein Phosphatases 1 and 2A Block the Sugar-Inducible Gene Expression in Plants.
Genes coding for two major proteins of the tuberous root of sweet potato (Ipomoea batatas), namely, sporamin and [beta]-amylase, are inducible in leaves and petioles when they are supplied with high concentrations of sucrose or other metabolizable sugars, such as glucose and fructose, and the accumulation of a large amount of starch accompanies this inductio

5. Light intensity regulation of cab gene transcription is signaled by the redox state of the plastoquinone pool.
The eukaryotic green alga Dunaliella tertiolecta acclimates to decreased growth irradiance by increasing cellular levels of light-harvesting chlorophyll protein complex apoproteins associated with photosystem II (LHCIIs), whereas increased growth irradiance elicits the opposite response. Nuclear run-on transcription assays and measurements of cab mRNA stabil
