Molecular parasitism in the Escherichia coli-Bdellovibrio bacteriovorus system: translocation of the matrix protein from the host to the parasite outer membrane.
During the intracellular maturation in Escherichia coli of the parasite Bdellovibrio bacteriovorus the outer membrane, major protein I of E. coli (i.e., the matrix protein) becomes associated with the outer membrane of the emerging parasite cells. The binding properties of this protein with the outer membrane of the host and of the parasite are identical. An analogous phenomenon also occurs during Bdellovibrio parasitism on Klebsiella pneumoniae and on Salmonella typhimurium. Possible roles for this scavenging action of Bdellovibrio, and similar phenomena in other parasitic systems, are discussed.
