| identification of a dna region from lactococcal phage sk1 protecting phage 712 from the abortive infection mechanism abif. | bacteriophage 712 is a small isometric-headed phage which is sensitive to the lactococcal abortive infection mechanism abif. its 29.6-kb dna genome was characterized by restriction mapping and transcriptional analysis. construction of a gene bank of lactococcal phage sk1, which is insensitive to the action of abif, in lactococcus lactis containing abif resulted in the identification of a 324-bp dna fragment which reduced the effect of the abortive infection mechanism on phage 712. analysis of th ... | 2000 | 10612752 |
