| protein ia and the lamb protein can replace each other in the constitution of an active receptor for the same coliphage. | protein ia and the lamb protein are both located in the outer membrane of escherichia coli k-12. the lamb protein is known to be the receptor for phage lambda. datta et al. [datta, d. b., arden, b. & henning, u. (1977) j. bacteriol. 131, 821--829] recently isolated a phage called tuia that uses protein ia for its adsorption. while phage tuia fails to grow on ompb mutants, which lack protein ia, we show here that host-range mutants of tuia can be isolated that do grow on ompb strains. these host- ... | 1978 | 364487 |
