Clustered regularly interspaced short palindrome repeats (CRISPRs) have spacers of extrachromosomal origin.
Numerous prokaryote genomes contain structures known as clustered regularly interspaced short palindromic repeats (CRISPRs), composed of 25-50 bp repeats separated by unique sequence spacers ofExpand
Identification and assembly of genomes and genetic elements in complex metagenomic samples without using reference genomes
Most current approaches for analyzing metagenomic data rely on comparisons to reference genomes, but the microbial diversity of many environments extends far beyond what is covered by referenceExpand
Pleiotropic transcriptional repressor CodY senses the intracellular pool of branched‐chain amino acids in Lactococcus lactis
Proteolysis is essential for supplying Lactococcus lactis with amino acids during growth in milk. Expression of the major components of the L. lactis proteolytic system, including the cell wallExpand
Transcriptional pattern of genes coding for the proteolytic system of Lactococcus lactis and evidence for coordinated regulation of key enzymes by peptide supply.
The transcription of 16 genes encoding 12 peptidases (pepC, pepN, pepX, pepP, pepA, pepF2, pepDA1, pepDA2, pepQ, pepT, pepM, and pepO1), P(I) and P(III) proteinases (prtP1 and prtP3), and threeExpand
Survival, Physiology, and Lysis ofLactococcus lactis in the Digestive Tract
ABSTRACT The survival and the physiology of lactococcal cells in the different compartments of the digestive tracts of rats were studied in order to know better the fate of ingested lactic acidExpand
An aminoacyl-tRNA synthetase paralog with a catalytic role in histidine biosynthesis.
In addition to their essential catalytic role in protein biosynthesis, aminoacyl-tRNA synthetases participate in numerous other functions, including regulation of gene expression and amino acidExpand
Molecular diversity and relationship within Lactococcus lactis, as revealed by randomly amplified polymorphic DNA (RAPD).
Lactococcus lactis strains are widely used in industrial dairy fermentations. Conventional phenotypic tests have been used for years to classify members of this species into two subspecies, lactisExpand
Low-redundancy sequencing of the entire Lactococcus lactis IL1403 genome
Lactococcus lactis is an AT-rich gram positive bacterium phylogenetically close to the genus Streptococcus. Various strains of L. lactis are used in dairy industry as starters for cheese making. L.Expand
BglR protein, which belongs to the BglG family of transcriptional antiterminators, is involved in beta-glucoside utilization in Lactococcus lactis.
A fragment of the Lactococcus lactis chromosome containing an open reading frame of 265 codons, denoted bglR, has been characterized. The polypeptide encoded by bglR shares 36 to 30% sequenceExpand
DNA restriction-modification systems mediate plasmid maintenance.
Two plasmid-carried restriction-modification (R-M) systems, EcoRI (from pMB1 of Escherichia coli) and Bsp6I (from pXH13 of Bacillus sp. strain RFL6), enhance plasmid segregational stability in E.Expand
