Spontaneous mutations in pcaH and -G, structural genes for protocatechuate 3,4-dioxygenase in Acinetobacter calcoaceticus.

Journal of bacteriology - 1 Mar 1995

Gerischer U, Ornston L N

Abstract excerpt

Bacteria containing spontaneous null mutations in pcaH and -G, structural genes for protocatechuate 3,4-dioxygenase, were selected by exposure of an Acinetobacter calcoaceticus strain to physiological conditions in which expression of the genes prevents growth. The parental bacterial strain exhibits high competence for natural transformation, and this procedure was used to characterize 94 independently isolated...
