[Adsorptive capacity of bacteriophage Mu on Escherichia coli K-12 strains with deletions in the attlambda region].
Escherichia coli strains with deletions in att lambda region were obtained. The comparison of the extent of deletions with the sensitivity of the corresponding mutant clones to phage Mu showed that the gene controlling the sensitivity of E. coli K-12 to the phage Mu is located in nad A-gal region of the bacterial chromosome. It is shown that the resistance of E. coli strains which had lost the region of bacterial chromosome between nad A gene and genes of gal-operon have adsorption character. Deletion of the nad A-gal region does not affect the adsorption of other phages (lambda, P1 and T4). Thus, the gene, located in this region, is responsible for the specific adsorption of the phage Mu.
