1. Production line performance analysis within a MTS/MTO manufacturing framework: a queueing theory approach
Abstract Paper aims Mixing the Make-To-Stock (MTS) and Make-To-Order (MTO) strategies to benefit from the both manufacturing systems in an environment with impatient customers. Originality This is the first research article which uses the queuing theory to find the best place of the Order Penetration Point (OPP) in a production line with impatient custom

2. Distribution and biological role of the oligopeptide-binding protein (OppA) in Xanthomonas species
In this study we investigated the prevalence of the oppA gene, encoding the oligopeptide binding protein (OppA) of the major bacterial oligopeptide uptake system (Opp), in different species of the genus Xanthomonas. The oppA gene was detected in two Xanthomonas axonopodis strains among eight tested Xanthomonas species. The generation of an isogenic oppA-knoc

3. Análise funcional das proteínas captadoras de molibdato (ModA) e oligopeptídeo (OppA) de Xanthomonas axonopodis pv. citri / Functional analysis of binding proteins of molybdate (ModA) and oligopeptide (OppA) from citri pv. citri
Molibdênio é um elemento traço envolvido na fixação de nitrogênio, enxofre e carbono. Oligopeptídeos estão envolvidos na nutrição bacteriana e diversos outros processos de sinalização intercelular. O objetivo do presente estudo foi investigar o papel funcional das proteínas ligadoras dos sistemas de captação de molibdato (ModA) e oligopeptíde

4. Gestão de estoques de produtos siderúrgicos semi-acabados utilizando uma abordagem híbrida de otimização e simulação
The inventory management is a vital subject witch frequently absorbs substantial part of the budget of an organization. As they do not add value to the product, as less inventories a productive system use more efficient it will be. However the current competitive environment, with the strong presence of global payers, forces the operational costs reduction,

5. Estudo do transporte de oligopeptídeos em Aeromonas hydrophila e comparação com outras espécies do gênero
O sistema de transporte de oligopeptídios (sistema Opp) está envolvido em diferentes aspectos da fisiologia bacteriana, incluindo nutrição, comunicação intercelular e fatores associados com a virulência. Estes transportadores ABC são formados por uma proteína de ligação a oligopeptídios, uma permease e um domínio de ligação ao ATP. As Aeromona

6. Genetic and biochemical characterization of the oligopeptide transport system of Lactococcus lactis.
The nucleotide sequence of a chromosomal DNA fragment of Lactococcus lactis subsp. lactis SSL135, previously implicated in peptide utilization, has been determined. The genes oppDFBCA, encoding the oligopeptide transport system (Opp), and that encoding the endopeptidase PepO were located on this 8.9-kb DNA fragment. The oppDFBCA and pepO genes are probably o

7. Specialized peptide transport system in Escherichia coli.
Trileucine is utilized as a source of leucine for growth of strains of Escherichia coli K-12 that are deficient in the oligopeptide transport system (Opp). Trithreonine is toxic to E. coli K-12. Opp- mutants of E. coli K-12 retain complete sensitivity to this tripeptide. Moreover, E. coli W, which is resistant to trithreonine, can utlize this tripeptide as a

8. Phaseolotoxin transport in Escherichia coli and Salmonella typhimurium via the oligopeptide permease.
Phaseolotoxin [(N delta-phosphosulfamyl)ornithylalanylhomoarginine], a phytotoxic tripeptide produced by Pseudomonas syringae pv. phaseolicola that inhibits ornithine carbamoyltransferase, is transported into Escherichia coli and Salmonella typhimurium via the oligopeptide transport system (Opp). Mutants defective in oligopeptide permease (Opp-) were resista

9. Escherichia coli K-12 Mutants Altered in the Transport Systems for Oligo- and Dipeptides
Two mutants of Escherichia coli K-12, defective in the oligopeptide and dipeptide transport system, are described. A mutant defective in the oligopeptide transport system (opp-1) was isolated as resistant to the inhibitory action of triornithine; this mutant is also resistant to glycylglycylvaline and does not concentrate 14C-glycylglycylglycine, although it

10. A Multifunction ABC Transporter (Opt) Contributes to Diversity of Peptide Uptake Specificity within the Genus Lactococcus
Growth of Lactococcus lactis in milk depends on the utilization of extracellular peptides. Up to now, oligopeptide uptake was thought to be due only to the ABC transporter Opp. Nevertheless, analysis of several Opp-deficient L. lactis strains revealed the implication of a second oligopeptide ABC transporter, the so-called Opt system. Both transporters are ex

11. Increase of sensitivity to aminoglycoside antibiotics by polyamine-induced protein (oligopeptide-binding protein) in Escherichia coli.
The sensitivity of Escherichia coli to several aminoglycoside antibiotics was examined with E. coli DR112 transformed by the gene for polyamine-induced protein (oligopeptide-binding [OppA] protein) or polyamine transport proteins. The results clearly showed that sensitivity to aminoglycoside antibiotics (gentamicin, isepamicin, kanamycin, neomycin, paromomyc

12. Relationship between Spontaneous Aminoglycoside Resistance in Escherichia coli and a Decrease in Oligopeptide Binding Protein
Changes in the amount of oligopeptide binding protein (OppA) in spontaneous kanamycin-resistant mutants of Escherichia coli were investigated. Among 20 colonies obtained from 108 cells cultured in the presence of 20 μg of kanamycin/ml, 1 colony had no detectable OppA and 7 colonies were mutants with reduced amounts of OppA. Sensitivity of wild-type cells to
