1. Identificação molecular de bactérias ácido láticas isoladas de leite cru e queijo, e pesquisa de genes de bacteriocinas / Molecular identification of lactic acid bacteria isolated from raw milk and cheese, and detection of bacteriocin genes
Considering the importance of the lactic acid bacteria (LAB) as biopreservatives, and their inhibitory potencial against pathogens and spoilage microrganisms, the aim of this study was identify using molecular methodologies LAB isolates obtained from raw milk and soft cheese, and to conduct a detailed study about the presence of bacteriocin codifying genes.

2. Perfil de aminoÃcidos nos frutos verdes do cafeeiro processados por via seca e via Ãmida / Amino acids profile in the unripe arabica fruits by dry and wet processing
The quality of natural coffee produced in Brazil is quite variable. During harvest, fruits at different stages of maturation can be found. Since manual and selective harvesting are economically prohibited, unripe fruits are naturally present in BrazilÂs post harvest. Processing operations can minimize this problem, providing correct processing techniques ar

3. Análise molecular do gene IAP de Listeria monocytogenes isoladas de alimentos no Rio Grande do Sul / Molecular analisys of iap gene of Listeria monocytogenes isolated from foods on Rio Grande do Sul
A bactéria Listeria monocytogenes é reconhecida como um importante patógeno humano estando amplamente distribuída no ambiente e é responsável pela contaminação de alimentos crus e processados. O mecanismo de patogenicidade é determinado pela presença de genes no cromossomo da bactéria e entre eles estão os genes iap e hly que são essenciais para

4. Limites minimos de sensibilidade e caracterização da qualidade de gosto para 21 aminoacidos
A determination of thresholds of difference and taste for 21 L-amino acids was carried out employing five concentrations with decreasing percentages in logarithmic scale and using distilled water as control. Three series of experiments were conducted using concentration ranges of 0.5 - 0.0312%; 0.125 - 0,0078% and 0.0078 - 0.0004%, respective1y. The tasting

5. A gamma methionine-310 to threonine substitution and consequent N-glycosylation at gamma asparagine-308 identified in a congenital dysfibrinogenemia associated with posttraumatic bleeding, fibrinogen Asahi.
In an abnormal fibrinogen with severely impaired polymerization of fibrin monomers, we identified a methionine-to-threonine substitution at position 310 of the gamma chain. Furthermore, asparagine at position 308 was found to be N-glycosylated due to a newly formed consensus sequence, asparagine(308)-glycine(309)-threonine(310). The two structural defects in

6. A Naturally Occurring Substitution in Human Immunodeficiency Virus Tat Increases Expression of the Viral Genome
A natural amino acid substitution in the human immunodeficiency virus type 1 (HIV-1) transcriptional activator Tat increases its activity and compensates for deleterious mutations elsewhere in the Tat protein. Substitution of asparagine for threonine 23 increases Tat transactivation of the HIV-1 promoter and the binding of Tat to the cellular kinase positive

7. Chemotaxis Toward Amino Acids in Escherichia coli
Escherichia coli cells are shown to be attracted to the l-amino acids alanine, asparagine, aspartate, cysteine, glutamate, glycine, methionine, serine, and threonine, but not to arginine, cystine, glutamine, histidine, isoleucine, leucine, lysine, phenylalanine, tryptophan, tyrosine, or valine. Bacteria grown in a proline-containing medium were, in addition,

8. Maturation cleavage required for infectivity of a nodavirus.
Nodaviral morphogenesis involves formation of labile precursor particles, called provirions, which mature by autocatalytic cleavage of the 407-residue coat precursor protein between asparagine residue 363 and alanine residue 364. It has previously been demonstrated that maturation results in increased physicochemical stability of the virion. We show here tha

9. Photosynthetic Formation of the Aspartate Family of Amino Acids in Isolated Chloroplasts 1
The metabolism of 14C-labeled aspartic acid, diaminopimelic acid, malic acid and threonine by isolated pea (Pisum sativum L.) chloroplasts was examined. Light enhanced the incorporation of [14C] aspartic acid into soluble homoserine, isoleucine, lysine, methionine and threonine and protein-bound aspartic acid plus asparagine, isoleucine, lysine, and threonin

11. Receptors for chemotaxis in Bacillus subtilis.
At least three receptors for chemotaxis toward L-amino acids in Bacillus subtilis could be found with the aid of taxis competition experiments. They are called the asparagine receptor, which detects asparagine and glutamine, the isoleucine receptor, which detects isoleucine, leucine, valine, phenylalanine, serine, threonine, cysteine, and methionine, and the

12. Amino Acid Metabolism of Lemna minor L. 1: I. Responses to Methionine Sulfoximine
When Lemna minor L. is supplied with the potent inhibitor of glutamine synthetase, methionine sulfoximine, rapid changes in free amino acid levels occur. Glutamine, glutamate, asparagine, aspartate, alanine, and serine levels decline concomitantly with ammonia accumulation. However, not all free amino acid pools deplete in response to this inhibitor. Several
