Abstract
A 5-kb DNA fragment conferring a phage abortive infection phenotype (Abi+) has been cloned from Lactococcus lactis subsp. lactis IL416. The Abi+ determinant was subcloned on a 2-kb fragment which carried an Iso-ISS1 element and an open reading frame of 753 bp designated ORFX. Deletion within ORFX entailed the loss of the Abi+ phenotype, establishing that ORFX is the structural abi-416 gene. The expression of abi-416 was shown to be mediated by the Iso-ISS1 element, which contains a sequence fitting the consensus sequence for gram-positive promoters.Entities:
