We examined the predacious gram-negative bacterium Bdellovibrio bacteriovorous 109J and free-living strains 109J-A1 and 109J-KA1 derived therefrom for penicillin-binding proteins (PBPs). We compared their PBPs with those of the host bacterium, Escherichia coli, and with those of a facultatively predacious bdellovibrio, B. stolpii UKi2, grown axenically. The multiple PBPs of the 109J strains and of UKi2 differed from each other and from those of E. coli, which suggests that screening for PBPs may be a convenient way to determine to what extent the bdellovibrios may represent a diverse group of organisms. A method for labeling furazlocillin and cefaperizone with iodine-125 is also described.
