M. Elmzibri et al., ADSORPTION OF PHAGE-LAMBDA TO SALMONELLA-TYPHIMURIUM LAMB(-MEMBRANE()REQUIRES THE PRESENCE OF LIPOPOLYSACCHARIDE IN THE OUTER), Biotechnology letters, 18(8), 1996, pp. 933-936
Two S. typhimurium strains TA1534 (rfa(+)) and TA1538 (rfaE) were tran
sformed with the lamB expression plasmid pAMH70. Transposition events
with lambda placMu55 hybrid phage were successful only with TA1534/pAM
H70 strain. Using SDS-PAGE, the LamB protein was present in the total
cell proteins but not in the outer membrane proteins of the TA1538/pAM
H70 strain. The LamB protein must linked to the LPS of the outer membr
ane to allow adsorption of lambda phage in S. typhimurium.
