Conservation of the pyrrolnitrin biosynthetic gene cluster among six pyrrolnitrin-producing strains.
[No authors listed]
摘要
The prnABCD gene cluster from Pseudomonas fluorescens encodes the biosynthetic pathway for pyrrolnitrin, a secondary metabolite derived from tryptophan which has strong anti-fungal activity. We used the prn genes from P. fluorescens strain BL915 as a probe to clone and sequence homologous genes from three other Pseudomonas strains, Burkholderia cepacia and Myxococcus fulvus. With the exception of the prnA gene from M. fulvus59% similar among the strains, indicating that the biochemical pathway for pyrrolnitrin biosynthesis is highly conserved. The prnA gene from M. fulvus is about 45% similar to prnA from the other strains and contains regions which are highly conserved among all six strains.
