Genetic Transformation System

ABSTRACTWe have constructed the firstEscherichia coli-Veillonellashuttle vector based on an endogenous plasmid (pVJL1) isolated from a clinicalVeillonellastrain. A highly transformableVeillonellastrain was also identified. Both the shuttle vector and the transformable strain should be valuable tools for futureVeillonellagenetic studies.

ABSTRACT Resistance to peptide deformylase inhibitors in Escherichia coli or Staphylococcus aureus is due to inactivation of transformylase activity. Knockout experiments in Streptococcus pneumoniae R6x indicate that the transformylase (fmt) and deformylase (defB) genes are essential and that adef paralog (defA) is not. Actinonin-resistant mutants of S. pneumoniae ATCC 49619 harbor mutations indefB but not in fmt. Reintroduction of the mutated defB gene into wild-type S. pneumoniaeR6x recreates the resistance phenotype. The altered enzyme displays decreased sensitivity to actinonin.
