Ralstonia pickettii T1 secretes a poly(3-hydroxybutyrate) (PHB) depolymerase (PhaZ) and a 3-hydroxybutyrate (3HB)-oligomer hydrolase, and extracellularly degrades PHB to produce 3HB. However, it is not clear how the expression of phaZ is regulated. In this study, the mechanism by which phaZ expression is controlled in R. pickettii T1 was examined using a mutant made by the random insertion of a transposon, Tn5. The mutant produced a larger amount of PhaZ than the wild type in nutrient broth or… CONTINUE READING
