Complete genome sequence and characterization of the haloacid–degrading Burkholderia caribensis MBA4

摘要

Burkholderia caribensis MBA4 was isolated from soil for its capability to grow on haloacids. This bacterium has a genome size of 9,482,704 bp. Here we report the genome sequences and annotation, together with characteristics of the genome. The complete genome sequence consists of three replicons, comprising 9056 protein-coding genes and 80 RNA genes. Genes responsible for dehalogenation and uptake of haloacids were arranged as an operon. While dehalogenation of haloacetate would produce glycolate, three glycolate operons were identified. Two of these operons contain an upstream glcC regulator gene. It is likely that the expression of one of these operons is responsive to haloacetate. Genes responsible for the metabolism of dehalogenation product of halopropionate were also identified.
