Zagotta, MT and Wilson, DB (1990) Oligomerization of the bacteriophage lambda S protein in the inner membrane of Escherichia coli. J. Bacteriol. 172:912-21

Abstract

Western blot (immunoblot) analysis of cell extracts from induced bacteriophage lambda lysogens probed with S-protein-specific antibody (raised against an S--beta-galactosidase fusion protein) demonstrated that the bacteriophage lambda S protein begins to appear 10 min after phage induction and is localized to the inner membrane at all times during the lytic cycle. Between 100 and 1,000 molecules of S protein per cell were present at the time of phage-induced lysis. Western blots of chemically cross-linked membranes from induced lysogens showed a ladder of bands at 18, 24, 32, and 42 kilodaltons (the S-protein monomer ran at 8 kilodaltons) that reacted with anti-S-protein antibody. Thus, the S protein appears to reside in the inner membrane as a multimer, and the molecular weights of the cross-linked species are consistent with those of S-protein homopolymers. Sodium dodecyl sulfate-resistant dimers were also detected when S protein was purified by immunoprecipitation.
