ptxD_opt

Most of the microorganisms, especially common used model organsims like Escherichia coli or Saccharomyces cerevisiae grow only very slow on phosphite as phosphorus source. Moreover in industry is not widely accepted to use antibiotic resistances as markers. Therefore a system is required, which allows avoidance of contamination by other microorganisms and at the same time represents a reliable selection marker. We present the use of the ptxD gene from Pseudomonas stutzeri together with a phosphite media, which could abolish the use of antibiotics in the future.


Usage and Biology

  • ptxD codes for phosphonate dehydrogenase
  • oxidation of phosphite (phosphonate) using NAD+ and H20 to phosphate and NADH
  • Selection marker for budding and fission yeast
  • phosphite-oxidizing ability
  • environmentally safe culture
  • antibiotic free system
  • pH optimum: 7.25- 7.75
