Project description:The bacterial tyrosine (BY) kinase family comprises the major group of bacterial enzymes endowed with tyrosine kinase activity. We have previously shown that the BceF protein from Burkholderia cepacia IST408 belongs to this BY kinase family and is involved in the biosynthesis of the exopolysaccharide cepacian. However, little is known about the extent of regulation in the cell by this kinase protein. In order to examine this, we performed a comparative transcriptome profile between the bceF mutant and the wild-type B. cepacia IST408. As a control, the transcriptome of another exopolysaccharide-deficient mutant, which had a mutation in the bceE gene, was also determined.
Project description:Burkholderia cepacia complex (Bcc) comprises opportunistic bacteria infecting hosts such as cystic fibrosis (CF) patients. Bcc long-term infection of CF patient airways has been associated with emergence of phenotypic variation. Here we studied two Burkholderia multivorans clonal isolates (D2095 and D2214) displaying different morphotypes from a chronically infected CF patient in order to evaluate traits development during lung infection. Since the custom array described in platform GPL13356 was based on Burkholderia multivorans ATCC 17616 genome, here we performed a DNA-DNA hybridization to determine which probes of the array hybridize with our test genomes
