Novel pathway for conversion of chlorohydroxyquinol to maleylacetate in Burkholderia cepacia AC1100.

abstract：:Natural isolates of pathogenic bacteria can exhibit a broad range of phenotypic traits. To investigate the molecular mechanisms contributing to such phenotypic variability, we compared the genomes, transcriptomes, and proteomes of two natural isolates of the gram-negative bacterium Burkholderia pseudomallei, the causa...
