The virulent lactococcal phage P087 was isolated from a dairy environment in 1978. This phage was then recognized as the reference member for one of the ten phage groups currently known to infect Lactococcus lactis strains. The double-stranded DNA ge

AbiP, a lactococcal abortive phage infection system, has previously been shown to arrest phage bIL66M1 DNA replication around 10 min after infection and to inhibit the switch off of phage early transcripts. We report here the functional characterizat

The virulent lactococcal phage KSY1 possesses a large elongated capsid (223 nm long, 45 nm wide) and a short tail (32 nm). This phage of the Podoviridae group (C3 morphotype) has a linear 79,232-bp double-stranded DNA genome, which encodes 131 putati

Three genes coding for a type I R-M system related to the class C enzymes have been identified on the chromosome of Lactococcus lactis strain IL1403. In addition, plasmids were found that encode only the HsdS subunit that directs R-M specificity. The

The function of the Lactococcus lactis bacteriophage bIL66 middle time-expressed operon (M-operon), involved in sensitivity to the abortive infection mechanism AbiD1, was examined. Expression of the M-operon is detrimental to Escherichia coli cells,

The lactococcal phage bIL41 belongs to the small isometric-headed phages of the 936 quasi-species and is resistant to the abortive infection determined by abiB. A 10.2-kb segment from this phage, in which late transcription is initiated, has been seq

The Lactococcus lactis subsp. lactis strains isolated from dairy products are auxotrophs for branched-chain amino acids (leucine, isoleucine, and valine), while most strains isolated from nondairy media are prototrophs. We have cloned and sequenced t

Resume Les phages sont reconnus depuis longtemps comme la principale cause de ralentissement de la croissance des lactocoques composant les levains de fromagerie. La selection de souches naturelles ou mutantes particulierement resistantes aux phages

Background Abortive infection (Abi) mechanisms comprise numerous strategies developed by bacteria to avoid being killed by bacteriophage (phage). Escherichia coli Abis are considered as mediators of programmed cell death, which is induced by infectin

Lactococcus lactis subsp. lactis NCDO 763 (also designated ML3) possesses an X-prolyl dipeptidyl aminopeptidase (X-PDAP; EC 3.4.14.5). X-PDAP mutants were selected by an enzymatic plate assay on the basis of their inability to hydrolyze an L-phenylal
