Pseudomonas stutzeri and related species undergo natural transformation.
Cells of Pseudomonas stutzeri are naturally transformed by homologous chromosomal DNA; they do not require chemical treatment to become competent. This capacity to undergo natural transformation was found to be shared by the closely related species P. mendocina, P. alcaligenes, and P. pseudoalcaligenes, but was not detectable in strains of P. aeruginosa, P. perfectomarinus, P. putida, P. fluore...
متن کاملPseudomonas stutzeri has two closely related pilA genes (Type IV pilus structural protein) with opposite influences on natural genetic transformation.
Pseudomonas stutzeri has type IV pili for which the pilA gene (here termed pilAI) provides the structural protein and which are required for DNA uptake and natural genetic transformation. Downstream of pilAI we identified a gene, termed pilAII, coding for a deduced protein with a size similar to that of PilAI with 55% amino acid sequence identity and with a typical leader peptide including a le...
متن کاملHigh Frequency of Natural Genetic Transformation of Pseudomonas stutzeri in Soil
Agar medium (SME) prepared from aqueous soil extract was used to examine genetic transformation of Pseudomonas stutzeri JM302 (his-i) by homologous his' DNA in a plate transformation assay. Growth studies indicated that SME was strongly limited in carbon and nitrogen sources. Transformation was observed on SME supplemented with pyruvate, phosphate, and ammonium. A 25-fold increase of the transf...
متن کاملImpact of mutS inactivation on foreign DNA acquisition by natural transformation in Pseudomonas stutzeri.
In prokaryotic mismatch repair the MutS protein and its homologs recognize the mismatches. The mutS gene of naturally transformable Pseudomonas stutzeri ATCC 17587 (genomovar 2) was identified and characterized. The deduced amino acid sequence (859 amino acids; 95.6 kDa) displayed protein domains I to IV and a mismatch-binding motif similar to those in MutS of Escherichia coli. A mutS::aac muta...
متن کاملMicrobial Transformation of Carbazole to Anthranilic Acid by Pseudomonas stutzeri.
This study examined the microbial transformation of carbazole (CZ) by an isolated bacterium that can use CZ as a sole carbon and nitrogen source. The strain identified as Pseudomonas stutzeri produced a large amount of anthranilic acid (AA) from CZ in the medium containing a nonionic surfactant. In dialysis culture using ion-exchange resin, 7.9 g/liter (58mm) of AA was accumulated from 15g/lite...
