Disruption of the Pseudomonas aeruginosa dipZ gene, encoding a putative protein-disulfide reductase, leads to a partial pleiotropic deficiency in c-type cytochrome biogenesis

Article Abstract:

Cloning and sequencing of the Pseudomonas aeruginosa dipZ gene was conducted to determine whether Escherichia coli dipZ (dsbD) is existing in pleitropically deficient organisms. The sequencing analysis was carried out by growing P. aeriginosa strains aerobically and subjecting the organism into a DNA analysis. Findings revealed that disruption of dipZ did not remove holo-c-type cytochromes. Furthermore, the inadequacy of dipZ to eradicate c-type cytochromes in Psedomonas aeruginosa leads to the analysis that the absence of dipZ can be balanced by other proteins.

Regulation of the gtfBC and ftf genes of Streptococcus mutans in biofilms in response to pH and carbohydrate

Article Abstract:

Research has been conducted on the Streptococcus mutans producing extracellular surcose-metabolizing enzymes that contribute to the fructosyltransferase encoded by ftf gene and glucosyltransferases produced by gtfB, gtfC and gtfD genes. The regulation of the expression of these genes has been investigated and the results are reported.

Carbohydrate sulfation effects on growth of Pseudomonas aeruginosa

Article Abstract:

Research has been conducted on the human pathogen Pseudomonas aeruginosa. The synthesis of the sulfated monosaccharides and the investigation of their role in the clinical isolates growth are discussed.
