FEMS Microbiol Lett 235:273-9. 2004..97%). Seventy-eight clones exhibited less than 95% of relatedness to NCBI database sequences, which may indicate the presence of new species in pulque samples...
Metabolic engineering for the production of shikimic acid in an evolved Escherichia coli strain lacking the phosphoenolpyruvate: carbohydrate phosphotransferase systemAdelfo Escalante
Departamento de Ingeniería Celular y Biocatálisis, Instituto de Biotecnologia, Universidad Nacional Autonoma de Mexico UNAM, Av, Universidad 2001, Col, Chamilpa, Cuernavaca, Morelos, 62210, Mexico
Microb Cell Fact 9:21. 2010..Derivatives of PB12 strain were constructed to determine the effects of inactivating aroK, aroL, pykF or pykA and the expression of plasmid-coded genes aroGfbr, tktA, aroB and aroE, on SA synthesis...
Growth recovery on glucose under aerobic conditions of an Escherichia coli strain carrying a phosphoenolpyruvate:carbohydrate phosphotransferase system deletion by inactivating arcA and overexpressing the genes coding for glucokinase and galactose permeasNoemí Flores
Departamento de Ingeniería Celular y Biocatálisis, Instituto de Biotecnologia, Universidad Nacional Autonoma de Mexico, Cuernavaca, Morelos, Mexico
J Mol Microbiol Biotechnol 13:105-16. 2007..However, the highest growth rate was obtained when glk and galP were overexpressed in the arcA(-) background. These results indicated that the arcA mutation enhanced glycolytic and respiratory capacities of the engineered strain...
Nutrient-scavenging stress response in an Escherichia coli strain lacking the phosphoenolpyruvate: carbohydrate phosphotransferase system, as explored by gene expression profile analysisSalvador Flores
Departamento de Ingeniería Celular y Biocatálisis, Instituto de Biotecnologia, Universidad Nacional Autonoma de Mexico, Cuernavaca, Mexico

New insights into the role of sigma factor RpoS as revealed in escherichia coli strains lacking the phosphoenolpyruvate:carbohydrate phosphotransferase systemNoemí Flores
Departamento de Ingeniería Celular y Biocatálisis, Instituto de Biotecnologia UNAM, Cuernavaca, Mexico
J Mol Microbiol Biotechnol 14:176-92. 2008..The role of RpoS in the transcription of these genes was analyzed and evidence that the expression of this group of genes could be regulated by a common factor in addition to RpoS was discussed...
