1998 journal article
A leucine repeat motif in AbiA is required for resistance of Lactococcus lactis to phages representing three species.
GENE, 212(1), 5–11.
author keywords: lactic acid bacteria; phage resistance; leucine zipper; dairy starter cultures
MeSH headings : Amino Acid Sequence; Amino Acid Substitution; Bacterial Proteins / chemistry; Bacterial Proteins / genetics; Bacterial Proteins / physiology; Bacteriophages / pathogenicity; Base Sequence; DNA Primers / genetics; Dairy Products / microbiology; Genes, Bacterial; Lactococcus lactis / genetics; Lactococcus lactis / virology; Leucine / genetics; Molecular Sequence Data; Mutagenesis, Site-Directed; Polymerase Chain Reaction; Repetitive Sequences, Nucleic Acid; Restriction Mapping; Species Specificity; Virulence
TL;DR:
Direct mutagenesis analysis of AbiA indicated that the leucine repeat structure is essential for conferring phage resistance against three species of lactococcal bacteriophages.

Control of expression of LlaI restriction in Lactococcus lactis
MOLECULAR MICROBIOLOGY, 27(5), 1009–1020.
MeSH headings : Amino Acid Sequence; Artificial Gene Fusion; Bacterial Proteins; Carrier Proteins / chemistry; Carrier Proteins / genetics; Cloning, Molecular; Gene Expression Regulation, Bacterial; Genetic Complementation Test; Lac Operon; Lactococcus lactis / enzymology; Lactococcus lactis / genetics; Molecular Sequence Data; Mutation; Open Reading Frames; Operon; Plasmids; Polymerase Chain Reaction; Promoter Regions, Genetic; Protein Biosynthesis; RNA / isolation & purification; RNA Processing, Post-Transcriptional; Site-Specific DNA-Methyltransferase (Adenine-Specific) / genetics; Transcription, Genetic
TL;DR:
Investigation of the effect of C·LlaI on enhancement of LlaI restriction in L. lactis revealed that growth at elevated temperatures (40°C) completely abolished any enhancement of restriction activity.

1997 journal article
A triggered-suicide system designed as a defense against bacteriophages
JOURNAL OF BACTERIOLOGY, 179(21), 6741–6748.
MeSH headings : Amino Acid Sequence; Bacteriophages / genetics; Bacteriophages / growth & development; DNA Restriction-Modification Enzymes / genetics; DNA Restriction-Modification Enzymes / metabolism; Genetic Engineering; Industrial Microbiology / methods; Lactococcus lactis / virology; Molecular Sequence Data; Site-Specific DNA-Methyltransferase (Adenine-Specific) / genetics; Site-Specific DNA-Methyltransferase (Adenine-Specific) / metabolism
TL;DR:
A novel bacteriophage protection system for Lactococcus lactis based on a genetic trap, in which a strictly phage-inducible promoter isolated from the lytic phage phi31 is used to activate a bacterial suicide system after infection, was developed.

1996 journal article
Development of an expression strategy using a lytic phage to trigger explosive plasmid amplification and gene expression
BIO-TECHNOLOGY, 14(1), 82–87.

IN-VIVO RESTRICTION BY LLAI IS ENCODED BY 3 GENES, ARRANGED IN AN OPERON WITH LLAIM, ON THE CONJUGATIVE LACTOCOCCUS PLASMID-PTR2030
JOURNAL OF BACTERIOLOGY, 177(1), 134–143.
MeSH headings : Amino Acid Sequence; Base Sequence; Blotting, Northern; Conjugation, Genetic; Conserved Sequence; DNA Mutational Analysis; DNA Restriction-Modification Enzymes / classification; DNA Restriction-Modification Enzymes / genetics; Frameshift Mutation; Genes, Bacterial / genetics; Lactococcus lactis / genetics; Molecular Sequence Data; Open Reading Frames / genetics; Operon / genetics; Plasmids / genetics; RNA, Bacterial / genetics; Sequence Analysis, DNA; Sequence Homology, Amino Acid; Site-Specific DNA-Methyltransferase (Adenine-Specific) / genetics
TL;DR:
The results suggested that the LlaI R/M system is unlike any other R/m system studied to date and has diverged from the type IIS class of restriction enzymes by acquiring some characteristics reminiscent of type I enzymes.

HIGH-COPY-NUMBER AND LOW-COPY-NUMBER LACTOCOCCUS SHUTTLE CLONING VECTORS WITH FEATURES FOR CLONE SCREENING
OSULLIVAN, D. J., & KLAENHAMMER, T. R. (1993, December 31). GENE, Vol. 137, pp. 227–231.
author keywords: ERYTHROMYCIN; LACZ-ALPHA COMPLEMENTATION; LACTIC ACID BACTERIA; STREPTOCOCCUS; THETA REPLICATION
MeSH headings : Cloning, Molecular / methods; Escherichia coli; Genetic Vectors; Lactococcus / genetics; Plasmids; Restriction Mapping
TL;DR:
High- and low-copy-number shuttle cloning vectors were constructed by incorporating the Escherichia coli P15A plasmid origin of replication into the pAM beta 1-derived vectors, pIL252 and pIL253 and displayed good structural stability in Lactococcus and E. coli.
