Regulation of Expression of the yiaKLMNOPQRS Operon for Carbohydrate Utilization in Escherichia coli : Involvement of the Main Transcriptional Factors

Autor: Evangelina Campos, Ester Ibañez, Laura Baldomà, Juan Aguilar, Josefa Badia

Publikováno v: Journal of Bacteriology. 182:4617-4624

The yiaKLMNOPQRS ( yiaK-S ) gene cluster of Escherichia coli is believed to be involved in the utilization of a hitherto unknown carbohydrate which generates the intermediate l -xylulose. Transcription of yiaK-S as a single message from the unique pr

Isoprenoid biosynthesis in Escherichia coli via the methylerythritol phosphate pathway: enzymatic conversion of methylerythritol cyclodiphosphate into a phosphorylated derivative of (E)-2-methylbut-2-ene-1,4-diol

Autor: Tore Duvold, Michel Rohmer, Albert Boronat, Ester Ibañez, Myriam Seemann, Narciso Campos, Manuel Rodríguez-Concepción, Denis Tritsch

Publikováno v: Tetrahedron Letters. 43:1413-1415

A crude cell-free system from an Escherichia coli strain overexpressing the cluster containing the three genes yfgA, yfgB, and gcpE converted 2-C-methyl- d -erythritol 2,4-cyclodiphosphate ( 1 ) into a phosphorylated derivative of (E)-2-methylbut-2-e

A mutant pyruvate dehydrogenase E1 subunit allows survival of Escherichia coli strains defective in 1-deoxy-D-xylulose 5-phosphate synthase

Publikováno v: FEBS letters. 580(3)

The 2-C-methyl-d-erythritol 4-phosphate pathway has been proposed as a promising target to develop new antimicrobial agents. However, spontaneous mutations in Escherichia coli were observed to rescue the otherwise lethal loss of the first two enzymes

Polyphosphate Kinase Protects Salmonella enterica from Weak Organic Acid Stress

Autor: Thomas G. Fazzio, Ester Ibañez Vallbona, John R. Roth, Marian Price-Carter

Mutants of Salmonella enterica lacking polyphosphate kinase ( ppk ) grow poorly in the presence of the weak organic acids acetate, propionate, and benzoate. This sensitivity is corrected by methionine and seems to result from destabilization of MetA

Genes yiaP and yiaR of the yiaKLMNOPQRS cluster of Escherichia coli are required for the metabolism of the endogenously formed l -xylulose, whereas yiaS is required for this metabolism only in araD mutants. Like AraD, YiaS was shown to have l -ribulo

The regulator of the yiaK-S operon, currently assigned a carbohydrate utilization function inEscherichia coli, is inactivated by a genome rearrangement that leads to the constitutive expression of the operon. TheyiaK-S constitutive cells acquire the
